The latest research shows that mental activity changes the brain and leads to what is known as “Wisdom.”

These latest findings are part of what is known:

Neuroplasticity.

For many years it was believed that after a certain age, the provision of neurons and are not renewable.

Recent research in neuroscience shows that the brain can be regenerated through use and promotion.
The key to this is called: “Neuroplasticity“, which is shaping the mind, brain, through the activity.

“The brain changes shape, according to the areas that we use, as mental activity.”

In March 2000, researchers at the University of London, found that taxi drivers in that city, were part of the brain, the hippocampus-region important for spatial memory, “particularly developed, much more than other people.
Taxi drivers developed over the area because exercising more, every day memorizing streets and roads.
In these men and women, their ability to memorize streets and roads not waned but increased with age.
In 2002 German scientists found the same findings in the Heschl gyrus of musicians, cerebral cortex area important for processing music … Read the rest of this entry »

When someone waves to them, our brain is capable of processing the gesture as something friendly and allows us to imitate. This is possible thanks to the mirror neuron system, a set of nerve cells, to date, it was thought that could go wrong in autistic spectrum disorders. However, a study published in ‘Neuron’ indicates that their normal activity in these patients.

The theory made sense. One of the most striking features of people with autism is their inability to imitation, empathy and understanding of the intent of the gestures of others. If mirror neurons are crucial for social interaction, it was logical to think that something is wrong with this brain system. In fact, some studies appeared to confirm the hypothesis.

But these works were overlooked something important. “No evaluated the selectivity of cortical activity in areas of particular movements mirror system,” says principal investigator, Ilan Dinstein, Department of Psychiatry at the University of New York (USA). This selectivity of movement is not simply the distinction that our brain makes every gesture, by storing a single neuronal response. Read the rest of this entry »
