Women's brains have more activity than men's

Contrary to what was stated in the past, science has shown in recent years that the differences between the brain of the woman and the man are not usually pronounced. However, there are some specific distinctions that are illuminated through research and that explain some particularities such as, for example, the greater or lesser tendency towards certain conditions, such as Alzheimer's.

  • 3 Increase in activity in the limbic zone
  • 4 Men's brains are active in specific areas

New research

The data obtained by a recent study carried out by scientists from Amen Clinics in California, they throw some of the keys that can explain certain differences between brains of different sexes.

These scientists carried out a study through which they analyzed 119 people without any psychiatric condition and 26683 people with different conditions related to the brain, such as brain trauma, ADHD or schizophrenia, among others.

While study participants rested or performed different concentration tasks, the scientists collected data on blood flow that they used in their brain, using the technique of Single photon emission computed tomography.

After analyzing the blood flow used by 128 brain regions of the participants, both when performing the tasks and when starting the study, the researchers found certain relevant data about the differences between the brains of women and men.

Women's brains are more active

These data yielded new information that until now had not been taken into account: women's brain had a greater blood flow than that of men in very important concrete areas.

One of these areas is the prefrontal cortex, an area of ​​the brain that plays a key role in cognitive processes such as information integration, planning, self-control and empathy. This area, the last to develop in the human brain, is something like an executive zone that allows us to carry out our decisions and our best adaptation to the environment.

The increase in blood flow that women presented in this area, indicates an increase in activity that may indicate that women may have greater ease in these related areas, such as targeting, planning, empathy or self-control.

Increase of activity in the limbic zone

The results also revealed an increase in activity in the limbic system. This has many components and structures very important for our survival such as amygdala, the hypothalamus the hippocampus and its main functions are related to the processes of memory and emotions. Both fear and other instinctive emotional responses, as well as addictions, find their center of operations in this brain zone.

This discovery may yield data on why women tend to have a higher risk of diseases such as Alzheimer's or other problems like the insomnia, the anxiety or depression to a greater extent.

As he explains Daniel Amen, director of the clinic “The quantifiable differences we identify between men and women are important for understanding gender-based risks for brain disorders such as Alzheimer's. Using neuroimaging tools, such as SPECT, is essential for the development, in the future, of precision medical treatments for the brain. ”

The brain of men is active in specific areas

Although the increase in activity was highly significant in women, the men's brain It also showed a specific increase, although not as significant in areas such as occipital lobe the inferior temporal lobe or cerebellum. This showed that the centers visual and coordination in men they were more active. The difference in activity also helps to understand why men show a greater tendency to suffer from disorders of Attention deficit and hyperactivity, as well as other disorders related to conduct.

Although these results are a small step forward in the study of the brain, more research is needed for these data to show their consistency. The brain is a great unknown, still difficult to understand today. Do not forget that regardless of gender, the human brain is a changing structure and malleable to the different experiences that can make its operation different depending on factors such as education or the context in which it develops.
