In new York, scientists have found that nerve cells of the brain are capable of regeneration even in the elderly. Thus they have refuted the widespread belief that “nerve cells do not regenerate”.
Employees of the University in new York found that some brain cells can regenerate even in the elderly, reports Rus.Media.
A team of scientists at Columbia University have refuted the widespread belief that “nerve cells do not regenerate”. To do this, they examined brain cells from 28 people at the age from 14 to 79 years, who died less than a day before the survey. Making surgical slices from all areas of the brain, they found new neurons, and their “germs” that have begun to regenerate from stem cells. Then they came to the conclusion that the human brain is able to regenerate even in old age.
However, in older people, new neurons are less plasticity. This leads to the worst interactions in neuronal connections, so they are not as useful as the nerve cells that appear in his youth.
It is noteworthy that about a month ago scientists at the University of California published a study which talked about the fact that in the brain of adults is not formed new neurons. But unlike their colleagues from new York, they examined the brains of people who died two days before the study, and made the cuts from all areas of the brain.
