Neuroscientists have learned the secret of centenarians

A group of American researchers from North-Western University, has studied the brains of centenarians. As a result, they found a feature which, apparently, increases the likelihood of living long enough to preserve the intellectual abilities in old age. One of the “secrets of longevity” were the so-called fusiform neurons

Spindle neurons, also known as neurons von Economo — large brain cells, allowing you to transfer it quickly, even by the standards of the “speed of thought”. In humans and humanoid primates, they are found in the anterior cingulate cortex and parts of the orbitofrontal cortex. Having studied the brains of people who have lived a very long life, experts came to the conclusion that they in the brain (especially the anterior cingulate cortex) of such neurons more than other people.

Researchers believe that these nerve cells allow some people not only live longer than others, but it is more efficient to maintain a strong mind in old age. So far, experts are not ready to clearly answer the question of how neurons contribute to spindle-like, however, suggest that further study of this question will allow you to deal more effectively with neurodegenerative diseases such as Alzheimer’s disease.

On the results, the scientists said at the recent conference of the American Association for the advancement of science.

Today, there are many theories of the aging brain, one of which involves the accumulation of random mutations in neurons, especially in brain areas where nerve cells are unable to divide.

Previously, various groups of researchers made the assumption that the average human lifespan in the future will continue to grow, but the likelihood that many people will live more than 116 years, will remain very low, and more than 125 years — and will tend to zero, if the human body would not be subjected to a kind of principled way.
