Brain work in summer and winter: what are the differences?

Scientists from the National Academy of Sciences of the United States found out that the human brain uses its cognitive functions in different ways during the year. Seasonality affects its work.

So what was the experiment about? Each of the 28 people who took part in the study went down to a bunker for several days, where they did not have information about the time of day or any other information about the outside world. There, each person was given tasks that stimulated his concentration of attention. At the same time, scientists studied the effectiveness of neuro activity of the people. During the experiment, scientists noted that the effectiveness of tasks depends to the season. For example, the highest levels of working memory were shown by the people in the autumn. For example the brain had to use more neural connections to solve the same tasks in June and in December. Minimal brain activity was observed in the spring.

Researchers suggest that such differences are possible with the dynamics of the production of neurotransmitters, such as serotonin.
