I'm not one of Bob Dylan's follower, so I don't know many of his songs. So I decided to ask my husband. He has told me some titles of his songs and I've decided on the first one, Knocknig on Heaven's Door, because I know it and I like it. But the first time I listened to this song, it was not Dylan who sang it, but another great musician: Eric Clapton. Bob Dylan does a great job, but I prefer Clapton.

THE C1 EXPERIENCE

Have you ever thought of a language course as an unforgettable voyage?

Well, there’s one: the C1!

Voyage to the C1

I started the C1 voyage as a tourist; I’m ending it as a traveller, though.

Now, contradictory feelings are flowing over me: it’s finished… Oh, no!

For sure, this has really been a very hard, long way till the desired goal,

But my soul has emotionally grown in the arms of creativity and flow…

Bob Dylan

Bob Dylan Still a Rolling Stone
Totally unpredictable as a tiny electron within an atom; completely changeable as a simple worm which turns into a beautiful butterfly, so has Bob Dylan been evolving throughout his whole life.
Unbelievably, Dylan’s musical career has kept evolving for almost 60 years and it continuous doing so. From acoustic to electric rhythms; from a Jewish to a Christian religiousness; from a folk to a pop style. But the primary essence of the artist still remains. His relentless and strong personality has made him not to stop working anytime.
 Always keeping abreast of the times, looking for new lyrics and different ways of expression, and showing a desire to sing for the people, neither a war nor an accident has prevented him from giving expression to his inner thoughts in an unprecedented poetic style. No musician has had a deeper impact on American popular music than him.
Now at 71, this diehard singer continues soldiering on, giving concerts around the world. Undoubtedly, “Rolling Stone” Dylan is still on the move.

THE RIGHT TO DIE WITH DIGNITY


 Here you have my oral presentation. It is about euthanasia. I know it is a very delicate issue and with a lot of controversies. I do not pretend that you agree with me. My only purpose is that you try to understand those who are in favour of euthanasia. Thank you in advance.
EUTHANASIA: THE RIGHT TO DIE WITH DIGNITY
                Today there are a great number of comatose patients in long term care facilities. There are countless elderly people in care facilities that have repeatedly expressed a desire to die. There are countless terminally ill patients that have also begged for death. Should these people be allowed to die or should they be forced to keep on living?
                In some countries, courts permit the administration of lethal injections to terminally ill patients. To many people, this is a barbaric practice. To others, it is the only human thing to do. When a person is dying of a terminal illness with no hope of recovery, that person should be allowed to die if they wish. Deliberately keeping them alive to endure the pain and suffering from their illness is the barbaric practice. If they wish death, death should be given to them. I firmly believe that the Right to Die is as sacred as the Right to Life.
                Aside from offering freedom from pain an undignified death that is prolonged and difficult for the patients and their families, the other serious issue that is a factor is that of freedom. We pride ourselves on the wide range of freedoms that impact our daily lives-- the right to speak freely, the right to live without threats, the right to pursue our own happiness—but what is happiness for someone with a terminal condition who is forced to live through the pain because the same government that allows other freedoms denies this one?
For some reason the ability to make a valid argument about euthanasia is stunted when the right to die is involved. In order to preserve our rights as human beings, it is necessary to stand up for this one because it is a matter of preservation of someone’s right to choose their own course, Happiness and ultimate fate.
                One of the controversies over the right to die is: Who should choose? If the patient is comatose or unable to make rational judgments, should the doctor or a family member permitted to make the final decision? If family members were allowed to make the final decision they could get away with the murder of a relative just because that person can’t make up their own mind.
However, there is a simple answer to this problem. Every person should have a “Living Will” which simply states that that person wishes death if they’re fatally injured or become terminally ill. A “Living Will” would permit people to make their own decisions about life and death with no possibility of being misunderstood.
                There are a huge number of people who are suffering from pain caused from terminal conditions yet that are forced to live out the rest of their lives in an undignified and unwanted way. I do not know why advocates of the Right to Life insist on keeping people who are suffering alive, but I do know they have no right to dictate a person whether or not they have the right to die.
I can understand their concern that euthanasia might be used for unethical killings but if euthanasia was strictly regulated to include those who had specifically asked for euthanasia, or those who had asked for it in living wills, then this kind of unethical practice could be prevented.
            When someone is suffering extreme pain from an injury or a terrible disease, do we deny tem drugs to make them more comfortable? Of course not. That’s why, I see no reason to deny the same suffering and dying people the comfort of death. I strongly believe helping them achieve a good death is a must for all of us.

Csíkszentmihályi

I'm having problems with my blog; it doesn`t work properly so the only thing I can do is to write. I don't know how to use links or how to insert a picture or a video. Everything has changed completely and I'm very bad at this kind of things. So please accept my apologies. Anyway, if you want to know more about
Csíkszentmihályi here you have more information.

Creativity—his own, others', and that of life itself—has been the entry point into evolution for Dr. Mihaly Csikszentmihalyi (pronounced "chick-sent-me-high-ee"). Truly an international renaissance man, born in Hungary, a graduate of the classical gymnasium "Torquato Tasso" in Rome, and an artist, Csikszentmihalyi earned his Ph.D. in psychology in 1965 from the University of Chicago, where he would eventually teach. Yet the bounds of psychology could contain neither his creativity nor his desire to find a greater order: "Somehow I always gravitated to the people in various disciplines—whether it's psychology, sociology, anthropology—who saw a certain unity in their field, who were not what later became known as postmodern reductionists," he explained, speaking on the telephone from his office at the Claremont Graduate University. Influenced by Carl Jung and reading widely in religion, Csikszentmihalyi found himself intrigued by "people who kind of stepped back and tried to say, 'What is it that's going on in this messy and confusing pattern of human behavior over time?' And I was influenced greatly, for instance, by Teilhard de Chardin, the Jesuit who developed this notion of evolution." Even his current position as a professor at Claremont's Drucker School of Management is a new evolutionary turn in a life lived with passion and curiosity.

Csikszentmihalyi is most well known for his bestselling 1990 book,
Flow: The Psychology of Optimal Experience. He defined and explored the concept of "flow"—as in "in the flow"—as our experience of optimal fulfillment and engagement. Flow, whether in creative arts, athletic competition, engaging work, or spiritual practice, is a deep and uniquely human motivation to excel, exceed, and triumph over limitation. Csikszentmihalyi describes his life's work as the effort "to study what makes people truly happy." The emphasis here is on the word "truly"—because to him, happiness is not simply flow nor an emotional state nor even the experience of pleasure. The happiness he points to involves the continual challenge to go beyond oneself as part of something greater than one's own self-interest.

What compelled us to speak to Dr. Csikszentmihalyi was his constantly evolving understanding of individual human development in the context of evolution. Ever the empiricist, he has systematically explored what it means to bring the laws of material evolution into both human and cultural development. In his books
The Evolving Self and Finding Flow, he develops a moral and ethical perspective on flow as a force of evolution. Integrating the concept of flow with a contemporary understanding of ancient wisdom teachings, he offers a new paradigm for human living rooted in his recognition that human beings now have the unique opportunity—and obligation—to become conscious participants in evolution. In the following interview, Dr. Csikszentmihalyi invites us to join in creating an evolutionary psychology founded in a deeper understanding of human motivation and an attention to our inescapable interconnectednes.

Flow with Soul


An interview with Dr. Mihaly Csikszentmihalyi
by Elizabeth Debold
 interview

WIE:
In your books The Evolving Self and Finding Flow, you speak about evolution, particularly about human evolution. Could you define what you mean by "evolution"?

MIHALY CSIKSZENTMIHALYI: At the most abstract level, what I mean by "evolution" is the increasing complexity of matter, which results in increasing possibility for consciousness. Here I'm differing from the view of [French Jesuit paleontologist] Teilhard de Chardin. He thought that rocks had a consciousness appropriate to their own material organization. I don't know whether they do or not, but his view was that whenever there is matter organized in some system, there is a commensurate level of consciousness, which reaches its apogee in the human nervous system being as it is the most intricate system, where you can code and store information of all different kinds. Smells, sights, inner feelings, and thoughts can all get stored because there is enough space, and the units are connected so that you can begin to draw parallels and see similarities and develop cause-and-effect relationships and so forth.

So you have this system that is very complexly organized, very intricately differentiated, and very integrated. Those are the two dimensions of complexity that you always see in evolution: differentiation and integration. Differentiation allows you to use different parts, for instance, different cells in your brain, different neurons to store information. And at the same time, these differentiated cells are connected to each other, or integrated, so that they can talk to each other, so to speak. Okay? They can exchange information. This is one way to talk about evolution: the process by which matter becomes more complex, allowing for more complex consciousness.

Then, of course, we see the results of humans becoming conscious begin to extend outside the body. And that's where we begin to see the evolution of culture, where we are able to store information not just in the brain but also in cave paintings and buildings, and then books and computers, etcetera. That begins to enlarge the amount of information about the universe that we can, in principle, deal with.

But I don't think the direction of evolution is laid down in any sense. We, having become aware of what is going on, have to decide for ourselves to what end this information should be directed and where it should be going. And I think that from the abstract level, the signposts for those decisions are again differentiation and integration. You want a future where people are free to develop whatever unique blueprints they carry in their genes, and you want that freedom to blossom as much as possible, but at the same time, you want each person to see that they are part of something much greater. That's where the integration comes in—it starts with feeling that you belong to a family, to an ethnic group, to a church and to a nation. But unless you realize that you're also part of all the living systems and the planet—that there is something beyond all of this that we can sense—unless you're part of that, then evolution would not be very successful, as far as I can tell.

Flow

Main article: Flow (psychology)
Mental state in terms of challenge level and skill level, according to Csikszentmihaly.
In his seminal work, Flow: The Psychology of Optimal Experience, Csíkszentmihályi outlines his theory that people are happiest when they are in a state of flow— a state of concentration or complete absorption with the activity at hand and the situation. It is a state in which people are so involved in an activity that nothing else seems to matter (Csikszentmihalyi,1990). The idea of flow is identical to the feeling of being in the zone or in the groove. The flow state is an optimal state of intrinsic motivation, where the person is fully immersed in what he or she is doing. This is a feeling everyone has at times, characterized by a feeling of great absorption, engagement, fulfillment, and skill—and during which temporal concerns (time, food, ego-self, etc.) are typically ignored.[8]
In an interview with Wired magazine, Csíkszentmihályi described flow as "being completely involved in an activity for its own sake. The ego falls away. Time flies. Every action, movement, and thought follows inevitably from the previous one, like playing jazz. Your whole being is involved, and you're using your skills to the utmost."[9]
To achieve a flow state, a balance must be struck between the challenge of the task and the skill of the performer. If the task is too easy or too difficult, flow cannot occur. Both skill level and challenge level must be matched and high; if skill and challenge are low and matched, then apathy results.[7]
The flow state also implies a kind of focused attention, and indeed, it has been noted that mindfulness, meditation, yoga, the Alexander Technique, and martial arts seem to improve a person's capacity for flow. Among other benefits, all of these activities train and improve attention.[citation needed]
In short, flow could be described as a state where attention, motivation, and the situation meet, resulting in a kind of productive harmony or feedback.[citation needed]

Teaching English as a Truly Foreign Language

This is a very interesting article I found in one of Emilio's links in his blog. It is about teaching English as a foreign language and I absolutely agree with some of the ideas in the article. What about you? Do you think the author is right or wrong?


The following question has been on my mind a lot recently: Why don't we teach English as a truly foreign language?
The background: Until recently I just took it for granted that in my teaching I should hold up the English of the native speaker as something my foreign students really ought to be aspiring to. It just seemed obvious to this British teacher that learners should become progressively more competent speakers of British English with all its idioms and odd ways of expressing things. There was no such thing as "English as a foreign language". There was just "teaching English as a foreign language", which meant a different method of teaching exactly the same language - pointing out things that would never need to be pointed out to native speakers, and putting a lot less emphasis on literature, for instance. And in this context it made sense to insist that students should be entered for EFL/ESL exams compiled back in the venerable city of Cambridge - and who better to set the standard than our colleagues on either side of the Cam? Of course there were also English exams organised by the Greek authorities (for students here in Greece), but one just smiled at them in a gently condescending way.
Increasingly I find that attitude (my own attitude) repugnant. Why hold up a Cambridge don or Robbie Williams or any other native speaker as a standard? Why not make it clear at the outset that this is English as a FOREIGN language - the language OF foreigners who, in all probablility, will never have the desire or the opportunity or the need to assimilate into some cosy English-speaking nook in Britain or elsewhere and, in a sense, disappear in some odd process of cultural and psychological self-abnegation?
This has become an issue for me particularly in connection with advanced classes of English language learners. At this level, I am becoming more and more doubtful about the value of teaching EXACTLY what the English natives say in a particular situation. Let me give an example. In a situation where someone needs to stay alert the native might use the expression: "Keep your eyes peeled." Now this is a colourful expression that I personally like and which it might be fun to present and discuss in class in one context or another. What I don't agree with any longer is the idea that if this expression cropped up in a course book, students should be expected to learn it by heart (perhaps for a quick vocab test the following day).
In my own vocab tests I would definitely include the more common use of the verb "peel" and the word's use as a noun, but I wouldn't expect students to learn the expression about peeling eyes, and I would certainly not include the latter in some test of whether they are proficient users of the language. If a foreign learner can talk about peeling onions and about your skin peeling when you get sunburnt, that for me is a mark of proficiency in English as a foreign language. With that know-how they will certainly be able to grasp the eye-peeling expression if they ever come across it.
But what will they say in a war zone where they need to tell someone to stay alert and be on the lookout for snipers if they don't know the expression "Keep your eyes peeled"? Well, I guess they could say: "Stay alert and be on the lookout for snipers." It does exactly the same job.
I would even be in favour of Greeks borrowing translated expressions from their own language to enrich the conversation. In Greek they say: "Keep your eyes 14." If you were in enemy territory with a Greek paratrooper and she turned to you and said: "As we say in Greek, 'Keep your eyes 14'." It would be obvious what the message was, and you might have learned an interesting detail about the Greek language. This, for me, is proficiency. Anyone who - between bursts of sniper fire - turned to the Greek woman and said: "If you don't already know the expression: 'Keep your eyes peeled' you can't really be proficient in English" would be a fool.
Of course, I am not in a position to say exactly what constitutes English as a foreign language. It seems to me that it really must be up to foreign organisations to define their own standards. This has led me to reverse my estimation of the local (Greek, in this case) examination authorities. There really needs to be a sea change - a massive upswelling of self-confidence in these local authorities to promote themselves and assert themselves and insist that they have the right to set the standards and answer the question: what should constitute proficiency for Greeks (in this case) who need to communicate in English with foreigners?
In the process there will hopefully be more freedom for Greeks (and all foreigners) to make the language their own. Another example springs to mind. Back in England a Greek colleague with excellent English quietly insisted on also using the word "sympathetic" in a Greek way (e.g. "It was a sympathetic film" meaning it was quite nice but not brilliant). It was obvious what she meant and I found this new (to the English) use of the word interesting. As long as there is no obstacle to communication, why shouldn't there be this freedom to use the language in ways that are foreign to the natives (heck, this is English as a Foreign Language, isn't it?).
Some will say that this is an unacceptable lowering of standards. I would reply that this objection fails to grasp the difference between teaching English as a native language, where there is a specific group of cultural and intellectual imperatives, and teaching English as a foreign language. For the native speaker the language is, to a certain extent, constitutive of their very being, their very identity (in a sense, you are what you say) whereas for the foreigner the language is likely to remain merely a tool of communication. As EFL teachers, we need to accept that and make sure that the tool is moulded adequately to the grip of the foreign learner.

Creativity: Its place in Education By Wayne Morris

Creativity: Its place in Education By Wayne Morris

This is the beginning of a very interesting article about creativity at schools. I haven't read it all yet.

“The roots of a creative society are in basic education. The sheer volume of facts to be digested by the students
of today leaves little time for a deeper interrogation of their moral worth. The result has been a generation of
technicians rather than visionaries, each one taking a career rather than an idea seriously. The answer must
be reform in our educational methods so that students are encouraged to ask about “know-why” as well as
“know-how”. Once the arts are restored to a more central role in educational institutions, there could be a
tremendous unleashing of creative energy in other disciplines too.”
Source: OnArts: Creative New Zealand. Michael D. Higgins, the former Irish Minister for
Arts, Culture and Gaeltacht
But is it enough to focus on the arts as the source of creativity in education?
Is there a much broader role for creativity in education?
“All our futures: Creativity, culture and education”, the UK National Advisory Committees
report [DfEE, 1999] defines creativity as:
“First, they [the characteristics of creativity] always involve thinking or behaving
Second, overall this imaginative activity is
objective. Third, these processes must generate something

the Disney Worldwide Outreach to produce materials that help teachers explore and
understand:
1. the role of creativity and innovation in teaching and learning
2. the importance of developing classroom and school environments that can bring out
the best in teachers and students, and
3. methods for making classrooms more engaging places
The following quote, from one of the teachers involved in the project, adds to the UK
definition.

“Although most people might look for signs of creativity in the appearance of the bulletin boards,
student made projects, centers and displays in the classroom, I feel the truly creative classroom goes way
beyond what can be seen with the eyes. It is a place where bodies and minds actively pursue new
knowledge. Having a creative classroom means that the teacher takes risks on a daily basis and
encourages his/her students to do the same.” Source: Pann Baltz quoted in Creativity in the

BODY LANGUAGE

This is the topic I'm going to talk about for the GESE exam (TRINITY ORAL EXAMINATION) next Friday. It's a very interesting topic, but I'm so nervous about the oral presentation, ... There are lots of interesting videos in Internet  and very good web pages. Here you have two of them:
http://helpguide.org/mental/eq6_nonverbal_communication.htm  
a very good resource

http://www.psychologydegree.net/resources/the-psychology-of-linguistics-and-body-language/

Excellent!

Nonverbal communication: body language
    1. Introduction. Has it ever occurred to you how much you are saying to people even when you are not speaking? Unless you are a master of disguise, you are constantly sending messages about your true thoughts and feelings whether you are using words or not. An image is worth 1,000 words. So, first, I'll define what body language is. Then, I'll explain some of the characteristics of this nonverbal language. And finally, I'll talk about the importance of body language in our present society.
    2. What is nonverbal communication and body language?
    * Body language is a language without spoken words and is therefore called non verbal communication. It is a vital form of communication—a natural, unconscious language that broadcasts our true feelings and intentions in any given moment, and clues us in to the feelings and intentions of those around us.
    - Several investigators estimate that at least 70% of the communication between people takes place through body language and the tone of voice. (The best known theory is that of the American psychologist Mehrabian. He states that when it comes to expressing feelings: 55% of the communication consists of body language, 38% is expressed through tone of voice and only 7% is communicated through words. If this is the case we express 93% of our feelings in a non-verbal way!)
    * Characteristics of body language.
    - Body language, unlike spoken language, is inexact; so you have to be careful about how you interpret it. A certain movement or facial expression may be quite meaningful, or it may mean nothing at all.
    - A lot of non-verbal behaviour is hereditary or is taught to everyone in the same way at a very young age. It is ingrained so to speak.
    This obviously means that we have to learn to recognise many gestures, which can mean one thing in one society and something else in another. Many body signals are not universal. (In most European countries and America for example, people shake their head when they mean no and nod when they mean yes, but there are cultures, for example in India or in Greece, where they mean the opposite - up and down means no and shaking means yes. The latter could be the evidence that this body language is taught rather than innate. )
    - Usually body language occurs unconsciously. It follows that therefore it would be good to become conscious of our own and others' body language. As I mention before, it is important to note that body language has different meanings in different cultures.
3. Why is body language so important?
* When we interact with others, we continuously give and receive wordless signals. All of our nonverbal behaviors — the gestures we make, the way we sit, how fast or how loud we talk, how close we stand, how much eye contact we make—send strong messages. Even when you’re silent, you’re still communicating non verbally. Looking at someone for example means something completely different than not looking at someone. In our contact with other people it is impossible not to communicate.
* You have probably heard many times that people remember more of what they see than what they hear. Long after a meeting, we are likely to have forgotten the exact words someone used, but we may retain a vivid image of the same person's facial expression. The way you listen, look, move, and react tells the other person whether or not you care, if you’re being truthful, and how well you’re listening.
* Through life experience we have learned, perhaps unconsciously, that people often lie with words. But facial expressions and other body language tend to be more honest. When a person's words and body language are consistent, we believe that person. When their words and body language say different things, we tend to believe the body language and doubt the words. When your nonverbal signals match up with the words you’re saying, they increase trust, clarity and rapport. When they don't, they generate tension, mistrust and confusion.
4. To sum up, body language has a larger reliability value When someone says something, information is conveyed through body language at the same time. This extra non-verbal information can support the content of the message or may contradict it. When someone contradict his words like this through his body language, his non-verbal message is almost always regarded as the most true because it is very difficult to lie through body language. However, most people are not very aware of their body language.
How we can interpret body language depends on the situation, the culture, the relationship we have with the person as well as the gender of the other. This means that there is not one signal that has the same meaning all over the world. If you do not take this into account, you may get yourself in some serious trouble!
Body language is one of the most powerful forms of human expression or human communication. You may not be aware of what you are saying with your body, but others will get the message. Make sure it's the one you want to send.

NEUROPLASTICITY

This is a very interesting topic, but very deep and difficult, as well. However, if you´re interested in this issue, here you can find information of your interest.


Definition of Neuroplasticity
Neuroplasticity: The brain's ability to reorganize itself by forming new neural connections throughout life. Neuroplasticity allows the neurons (nerve cells) in the brain to compensate for injury and disease and to adjust their activities in response to new situations or to changes in their environment.
Brain reorganization takes place by mechanisms such as "axonal sprouting" in which undamaged axons grow new nerve endings to reconnect neurons whose links were injured or severed. Undamaged axons can also sprout nerve endings and connect with other undamaged nerve cells, forming new neural pathways to accomplish a needed function.
For example, if one hemisphere of the brain is damaged, the intact hemisphere may take over some of its functions. The brain compensates for damage in effect by reorganizing and forming new connections between intact neurons. In order to reconnect, the neurons need to be stimulated through activity.
Neuroplasticity sometimes may also contribute to impairment. For example, people who are deaf may suffer from a continual ringing in their ears (tinnitus), the result of the rewiring of brain cells starved for sound. For neurons to form beneficial connections, they must be correctly stimulated.
Neuroplasticity is also called brain plasticity or brain malleability.

Brain Plasticity--An Overview

What is brain plasticity? Does it mean that our brains are made of plastic? Of course not. Plasticity, or neuroplasticity, is the lifelong ability of the brain to reorganize neural pathways based on new experiences. As we learn, we acquire new knowledge and skills through instruction or experience. In order to learn or memorize a fact or skill, there must be persistent functional changes in the brain that represent the new knowledge. The ability of the brain to change with learning is what is known as neuroplasticity.
To illustrate the concept of plasticity, imagine the film of a camera. Pretend that the film represents your brain. Now imagine using the camera to take a picture of a tree. When a picture is taken, the film is exposed to new information -- that of the image of a tree. In order for the image to be retained, the film must react to the light and ?change? to record the image of the tree. Similarly, in order for new knowledge to be retained in memory, changes in the brain representing the new knowledge must occur.
To illustrate plasticity in another way, imagine making an impression of a coin in a lump of clay. In order for the impression of the coin to appear in the clay, changes must occur in the clay -- the shape of the clay changes as the coin is pressed into the clay. Similarly, the neural circuitry in the brain must reorganize in response to experience or sensory stimulation.

Facts About Neuroplasticity

FACT 1: Neuroplasticity includes several different processes that take place throughout a lifetime.
Neuroplasticity does not consist of a single type of morphological change, but rather includes several different processes that occur throughout an individual?s lifetime. Many types of brain cells are involved in neuroplasticity, including neurons, glia, and vascular cells.
FACT 2: Neuroplasticity has a clear age-dependent determinant.
Although plasticity occurs over an individual?s lifetime, different types of plasticity dominate during certain periods of one?s life and are less prevalent during other periods.
FACT 3: Neuroplasticity occurs in the brain under two primary conditions:
1. During normal brain development when the immature brain first begins to process sensory information through adulthood (developmental plasticity and plasticity of learning and memory).
2. As an adaptive mechanism to compensate for lost function and/or to maximize remaining functions in the event of brain injury.
FACT 4: The environment plays a key role in influencing plasticity.
In addition to genetic factors, the brain is shaped by the characteristics of a person's environment and by the actions of that same person.

Developmental Plasticity: Synaptic Pruning

Gopnick et al. (1999) describe neurons as growing telephone wires that communicate with one another. Following birth, the brain of a newborn is flooded with information from the baby?s sense organs. This sensory information must somehow make it back to the brain where it can be processed. To do so, nerve cells must make connections with one another, transmitting the impulses to the brain. Continuing with the telephone wire analogy, like the basic telephone trunk lines strung between cities, the newborn?s genes instruct the "pathway" to the correct area of the brain from a particular nerve cell. For example, nerve cells in the retina of the eye send impulses to the primary visual area in the occipital lobe of the brain and not to the area of language production (Wernicke?s area) in the left posterior temporal lobe. The basic trunk lines have been established, but the specific connections from one house to another require additional signals.
Over the first few years of life, the brain grows rapidly. As each neuron matures, it sends out multiple branches (axons, which send information out, and dendrites, which take in information), increasing the number of synaptic contacts and laying the specific connections from house to house, or in the case of the brain, from neuron to neuron. At birth, each neuron in the cerebral cortex has approximately 2,500 synapses. By the time an infant is two or three years old, the number of synapses is approximately 15,000 synapses per neuron (Gopnick, et al., 1999). This amount is about twice that of the average adult brain. As we age, old connections are deleted through a process called synaptic pruning.
Synaptic pruning eliminates weaker synaptic contacts while stronger connections are kept and strengthened. Experience determines which connections will be strengthened and which will be pruned; connections that have been activated most frequently are preserved. Neurons must have a purpose to survive. Without a purpose, neurons die through a process called apoptosis in which neurons that do not receive or transmit information become damaged and die. Ineffective or weak connections are "pruned" in much the same way a gardener would prune a tree or bush, giving the plant the desired shape. It is plasticity that enables the process of developing and pruning connections, allowing the brain to adapt itself to its environment.

Plasticity of Learning and Memory

It was once believed that as we aged, the brain?s networks became fixed. In the past two decades, however, an enormous amount of research has revealed that the brain never stops changing and adjusting. Learning, as defined by Tortora and Grabowski (1996), is ?the ability to acquire new knowledge or skills through instruction or experience. Memory is the process by which that knowledge is retained over time.? The capacity of the brain to change with learning is plasticity. So how does the brain change with learning? According to Durbach (2000), there appear to be at least two types of modifications that occur in the brain with learning:
  1. A change in the internal structure of the neurons, the most notable being in the area of synapses.
  2. An increase in the number of synapses between neurons.
Initially, newly learned data are "stored" in short-term memory, which is a temporary ability to recall a few pieces of information. Some evidence supports the concept that short-term memory depends upon electrical and chemical events in the brain as opposed to structural changes such as the formation of new synapses. One theory of short-term memory states that memories may be caused by ?reverberating? neuronal circuits -- that is, an incoming nerve impulse stimulates the first neuron which stimulates the second, and so on, with branches from the second neuron synapsing with the first. After a period of time, information may be moved into a more permanent type of memory, long-term memory, which is the result of anatomical or biochemical changes that occur in the brain (Tortora and Grabowski, 1996).

Injury-induced Plasticity: Plasticity and Brain Repair

During brain repair following injury, plastic changes are geared towards maximizing function in spite of the damaged brain. In studies involving rats in which one area of the brain was damaged, brain cells surrounding the damaged area underwent changes in their function and shape that allowed them to take on the functions of the damaged cells. Although this phenomenon has not been widely studied in humans, data indicate that similar (though less effective) changes occur in human brains following injury.

They said it!
"The principal activities of brains are making changes in themselves."

Neuroplasticity: Your Brain’s Amazing Ability to Form New Habits

One of the most popular areas of research in psychology these days is neuroplasticityNeuroplasticity refers to the brain’s ability to restructure itself after training or practice.  In many ways, neuroplasticity is what makes personal growth and development possible at its most basic level.  With the understanding that change is indeed possible, you’re able to focus on the ways in which you’d like to grow instead of whether or not it’s achievable for you.  It’s possible, it’s proven, and now it’s up to you!
We are what we repeatedly do.  Excellence, then, is not an act, but a habit. – Aristotle
An example of how neuroplasticity works: when you view the brains of people who frequently practice playing the violin under fMRI (functional MRI) they appear to have developed a larger area of their brain devoted to mapping their fingers.  This change is directly related to the quantity and the quality of the practice they’re performing – their brains are adapting in very real and tangible ways unbeknownst to them.
One of the fun sayings around neuroplasticity: “neurons that fire together wire together… and neurons that fire apart wire apart.”.  Effectively this means that when neurons activate at the same time as a response to an event, the neurons become associated with one another and the connections become stronger.  This is why people talk about “neural pathways being set” with respect to increased practice – the more practice you accumulate, the more ingrained or grooved the pathways become.  Of course the inverse happens as well: if those pathways aren’t utilized, the space will be used by other pathways needing room to grow. Use it or lose it!
You can picture this yourself by imagining the flow of water through sand (I’m writing this from a beach in Kauai so excuse the metaphor – but I always find a mental motion picture is worth a thousand words!)  When seawater first runs over the sand, there isn’t a path for it to follow so it starts to form one for itself.  As the water continues to flow over the sand, the pathway forms a real groove in the sand and gets deeper and more defined.  It may start to branch off and take up more room in the sand if necessary, even reforming pathways on top of pathways that are no longer in use if it needs to.  Once the pathways are formed, it becomes more difficult to change the water flow – and if the water ever stops flowing, the pathway will remain for some time in the hopes that it’ll be used again at some point.  (This is why picking something back up after some time of inactivity is easier than starting a new activity cold).
The research around neuroplasticity is burgeoning these days – many people in psychology are talking about the hows and whys around it, and over the last decade a fair amount of research has already been done on the brain and its ability to reshape itself.  It’s no longer considered a theory in brain science, it’s fact.  Up until the 1980s or early 1990s, most scientists believed that your brain developed in your early years (throughout childhood) and then became “hardened” like dried concrete.  One has to assume this is where the moniker, “you can’t teach an old dog new tricks” came from.  But it turns out this just isn’t true.  You can fundamentally change your brain so long as oxygen and blood is flowing through you.  Which means you have no excuse when it comes to forming new habits.
In Tibetan Buddhism, the concept of neuralplasticity has been around for far longer than Western science has recognized it – the term for it is le-su-rung-wa which means “pliability”; your brain can change based on repeated experience. It’s no surprise then that studies have been performed on plasticity during meditation and have shown that the brain can change based purely on mental training.  This of course has huge ramifications for mental practice and its impact on overall well-being.  If you can think yourself into being more compassionate, or more positive and more resourceful, or calmer and more content, it seems a little too good to be true.  But with some effort, it’s possible.
There are a few interesting things to note about neuroplasticity.  Change takes place rather suddenly in the brain.  A recent study has shown that habits can be formed in as little as 7 days of repeated activity, but can dissipate just as easily.  In other words, change comes naturally and quickly and can disappear just as quickly as it arrived.  It also appears that “learning a variety of new things, rather than simply practicing old skills, may be most effective in terms of brain structure alterations”.  And while neuroplasticity is possible in adults, it appears that in children it’s rampant – which makes logical sense as it aligns with our overall perspective on learning.
In short: this is relevant research to all of us.  It implies that people of any age have the ability to learn new things and form new habits.  Therefore contentment (my preferred term for ‘happiness’) isn’t a state you’re born into, it’s a state you can discover.  And the sky’s the limit for the ability to learn and perfect new things throughout your life.
So what are you waiting for?

For decades, scientists thought that the adult human brain was static and unchanging. But in the last few decades, we have learned that the adult brain is more dynamic than we ever imagined!
