American scientists from Northwestern University set out to understand why long-livers do not lose cognitive abilities even at a deeply advanced age.

As a result, they found a special feature of the brain in such people.

After examining the brain of a group of long-livers, specialists discovered in it a surprisingly high amount of spindle-shaped neutrons. This is a relatively rare type of large neurons that are activated in the cerebral cortex. Their "inclusion" provides a direct and rapid connection between the far-lying parts of the brain.

According to scientific data, spindle-shaped neurons begin to form later than all others - only from the 35th week of pregnancy. At the time of the birth of a child, their number does not exceed 15% of the final number, but by the 8th month of life there has been a rapid growth. Then the total number of neurons decreases smoothly - in a four-year-old child fusiform neurons in the brain are formed already in the form in which they will be in him and in adulthood.

But the analysis of spindle-like neurons in the brain of long-livers has shown that the volume of this kind of neurons is several times higher than that of 20-year-old people. When the brain of long-livers was compared with the brains of people 50-60 years old, it was found that in the latter, the area of ??spindle-shaped neurons is much thinner.

While there is no exact answer, why is this happening.

But if you consider that spindle-shaped neurons are responsible for maintaining active thinking, memory, and communicative abilities, it's easy to imagine why the brain of long-livers, who have more of these neurons - can be much more intelligent in their productivity than the brains of people of young generations.

Studies of the nature of the formation of such brain cells will be continued, experts said..

As reported, the American, who celebrated her 104th birthday on January 1, told what she believes is the secret of longevity.
