"[In the brain are neurons.] Each neuron has three parts: the dendrites, the cell body, and the axon. The dendrites are treelike branches that receive input from other neurons. The dendrites lead into the cell body, which sustains the life of the cell and contains its DNA. Finally, the axon is a living cable of varying lengths (from microscopic ones in the brain to others that run down to the legs and can be three feet long). Axons are often compared to wires because they carry electrical impulses at very high speeds (from 2 to 200 miles per hour) toward the dendrites of neighboring neurons. A neuron can receive two kinds of signals: ones that excite it (excitatory signals) and ones that inhibit it (inhibitory signals). When a neuron receives enough excitatory signals, it will fire off its own signal. When it receives enough inhibitory signals, it becomes less likely to fire.
Axons don't quite touch the neighboring dendrites. They are separated by a microscopic space called a synapse. Once an electrical signal gets to the end of the axon, it triggers the release of a chemical messenger, called a neurotransmitter, into the synapse. The chemical messenger floats over to the dendrite of the adjacent neuron, exciting or inhibiting it. When we say that neurons 'rewire' themselves, we mean that alterations occur at the synapse, strengthening and increasing, or weakening and decreasing, the number of connections between the neurons.
One of the core laws of neuroplasticity is that neurons that fire together wire together, meaning that repeated mental experience leads to structural changes in the brain neurons that process that experience, making the synaptic connections between those neurons stronger. In practical terms, when a person learns something new, different groups of neurons get wired together. As a child learns the alphabet, the visual shape of the letter A is connected with the sound 'ay.' Each time the child looks at the letter and repeats the sound, the neurons involved 'fire together' at the same time, and then 'wire together'; the synaptic connections between them are strengthened. Whenever any activity that links neurons is repeated, those neurons fire faster, stronger, sharper signals together, and the circuit gets more efficient and better at helping to perform the skill.
The converse is also true. When a person stops performing an activity for an extended period, those connections are weakened, and over time many are lost. This is an example of a more general principle of plasticity: that it is a use-it-or-lose-it phenomenon. Thousands of experiments have now demonstrated this fact. Often the neurons that were involved in the skill will be taken over and used for other mental tasks that are now being performed more regularly. Sometimes one can manipulate the use-it-or-lose-it principle to undo brain connections that are not helpful, because neurons that fire apart wire apart. Suppose a person has formed a bad habit of eating whenever he is emotionally upset, associating the pleasure of food with the dulling of emotional pain; breaking the habit will require learning to disassociate the two. He might have to actively forbid himself from going to the kitchen when he is emotionally upset, until he finds a better way to handle his emotions. ...

"After the initial critical learning period of youth is over, the areas of the brain that need to be 'turned on' to allow enhanced, long lasting learning [including associative memorizing] can only be activated when something important, surprising, or novel occurs, or if we make the effort to pay close attention [and focus intently]." - Dr. Norman Doidge

"One reason we can change our brains simply by imagining is that, from a neuroscientific point of view, imagining an act and doing it are not as different as they sound. When people close their eyes and visualize a simple object, such as the letter a, the primary visual cortex lights up, just as it would if the subjects were actually looking at the letter a. Brain scans show that in action and imagination many of the same parts of the brain are activated. That is why visualizing can improve performance. ...imagining an act engages the same motor and sensory programs that are involved in doing it. We have long viewed our imaginative life with a kind of sacred awe: as noble, pure, immaterial, and ethereal, cut off from our material brain. Now we cannot be so sure about where to draw the line between them. Everything your 'immaterial' mind imagines leaves material traces. Each thought alters the physical state of your brain synapses at a microscopic level. Each time you imagine moving your fingers across the keys to play the piano, you alter the tendrils in your living brain." - Dr. Norman Doidge

"[Learning and memory:] If you want to lift a hundred pounds, you don't expect to succeed the first time. You start with a lighter weight and work up little by little. You actually fail to lift a hundred pounds, every day, until the day you succeed. But it is in the days when you are exerting yourself [persisting] that the growth is occurring." - Norman Doidge

"[The human brain is truly remarkable, in particular our imagination. Here is information that suggests that merely imagining something can help the brain rewire its neurons to learn and improve not only mental performance but, in these reports of two experiments, physical performance as well!]
Pascual-Leone taught two groups of people, who had never studied piano, a sequence of notes, showing them which fingers to move and letting them hear the notes as they were played. Then members of one group, the 'mental practice' group, sat in front of an electric piano keyboard, two hours a day, for five days, and imagined both playing the sequence and hearing it played. A second 'physical practice' group actually played the music two hours a day for five days. Both groups had their brains mapped before the experiment, each day during it, and afterward. Then both groups were asked to play the sequence, and a computer measured the accuracy of their performance.
Pascual-Leone found that both groups learned to play the sequence, and both showed similar brain map changes. Remarkably, mental practice alone produced the same physical changes in the motor system as actually playing the piece. By the end of the fifth day, the changes in motor signals to the muscles were the same in both groups, and the imagining players were as accurate as the actual players were on their third day.
The level of improvement at five days in the mental practice group, however substantial, was not as great as in those who did physical practice. But when the mental practice group finished its mental training and was given a single two-hour physical practice session, its overall performance improved to the level of the physcial practice group’s performance at five days. Clearly mental practice is an effective way to prepare for learning a physical skill with minimal physical practice...
In an[other] experiment that is as hard to believe as it is simple, Drs. Guang Yue and Kelly Cole showed that imagining one is using one’s muscles actually strengthens them. The study looked at two groups, one that did physical exercise and one that imagined doing exercise. Both groups exercised a finger muscle, Monday through Friday, for four weeks. The physical group did trials of fifteen maximal contractions, with a twenty-second rest between each. The mental group merely imagined doing fifteen maximal contractions, with a twenty-second rest between each, while also imagining a voice shouting at them, 'Harder! Harder! Harder!'
[The results? The subjects who actually did the physical exercise got 30 percent stronger at the end of the training period. The subjects who only did the imaginary exercise got 22 percent stronger.
So over training periods of several weeks, purely imaginary practice can lead to changes in the brain and increases in physical performance that nearly match the effect of actually, physically practicing.
The mechanism behind this is as simple as it is fascinating: as far as your brain is concerned, merely imagining doing something is very nearly the same as actually doing it. Experiments have confirmed that imagining an image causes your brain to go through the same pattern of firing and activation that it does when you actually see the same image. Watching a person shoot a basketball causes the same brain areas to light up that are involved in shooting a basketball.
The implications behind what we are learning from research into this power of our imaginations are potentially huge for learning and improving all sorts of physical skills, in particular for athletes and even for workers.]" - Dr. Norman Doidge

"Language development, for instance, has a critical period that begins in infancy and ends between eight years and puberty. After this critical period closes, a person's ability to learn a second language without an accent is limited. In fact, second languages learned after the critical period are not processed in the same part of the brain as is the native tongue." - Norman Doidge
