Some brain cells are updated continuously.
American scientists have discovered that brain cells recover equally as the elderly and the young.
Until the middle of last century believed that the new neurons in adult mammals are not born. The death of nerve cells kompensiruet at the expense of redistribution of functions among the rest.
“In the hippocampus of elderly people can form the same tens of thousands of new neurons as in the brain of young people. This is supported by the fact that the volume of the center of memory in the elderly and young people was about the same. On the other hand, vessels worse been feeding him blood, and the neurons may have formed fewer ties,” says Maura Boldrini from Columbia University in new York. The results of a study published in the journal Cell Stem Cell.
