Scientists name the professions that reduce brain volume

Scientists from Russia, the United States and Belgium claim that careers affect the growth and death of brain cells.

Who has the most shrinking brain?

It was discovered that: the human brain begins to shrink when it has to perform many monotonous repetitive activities . Scientists say astronauts are the first in this risk group. Even a short time in the weightless state reduces the size of the brain lobe and moves them, in addition, the flow of cerebrospinal fluid decreases and the overall rate of activity decreases by 3.3%.

Astronauts are the first people in the group with the most shrinking brains.

In which case does the brain increase volume?

Taxi drivers' brains change. However, they have the opposite effect - it grows. In the brains of motorists, the process of change in the hippocampus occurs, the brain creates new neurons. This part is responsible for memory, it grows because of the need to remember many routes. However, when using the navigation, this effect is completely eliminated.

The intellectual career is not the end

Even professional chess players are at risk of brain reduction. However, it is not high. Experts have found that representatives of this profession have smaller occipital lobe sizes, because they are not so important to their activities. These areas help shape ideas about each other. Similar changes have been observed in linguists.

For music artists, there are signs of increased brain lobe responsible for the movement of the fingers. Therefore, an experienced violinist will have more cortical mass associated with small motor skills.
