Scientists have found evidence that physical activity positively affect the brain of the child. In the nervous system gets more oxygen, increases the quality and speed of transmission of nerve impulses.
Research group of the University of Illinois established that children who regularly engaged in sports, in the brain contain a greater volume of white matter, which, as you know, is responsible for signal transmission along the nerve fibers.
Certain areas of the white matter determines the quality of the attention and memory of the child.
This discovery is the first of its kind. Usually scientists are studying the cerebral cortex and the mechanisms of its formation.
