WOMEN’S BRAINS ARE MORE ACTIVE THAN MEN’S
This is not new, women and men are different both biologically and psychologically. And to abound in this sense, as some articles already present on our Health Nutrition Blog, the largest functional study of brain imaging to date has recently identified specific brain differences between women and men.
BETTER UNDERSTAND THE DIFFERENCES BETWEEN THE BRAIN OF THE WOMAN AND THAT OF THE MAN
A report published on August 4, 2017 in the journal Journal of Alzheimer’s Disease details the results of the largest functional study on brain imaging to date – Amen Clinics (Newport Beach, CA) compared 46,034 imaging studies by the brain using TEMP (single emission tomography), provided by 9 clinics, quantifying the differences between the brains of men and women.
This is a very important study to help understand gender-based brain differences, which I personally enjoy, because as you should realize if you regularly follow my health blog, I am very attracted to information about the brain and neurology (and not just green tea !).
The quantifiable differences identified between men and women are important for understanding gender-based risk for brain disorders such as neurodegenerative diseases such as Alzheimer’s disease . The use of functional neuroimaging tools, such as single photon emission tomography (TEMP), is essential to develop precision treatments in the future, researchers point out.
THE PREFRONTAL CORTEX OF THE WOMAN IS MORE ACTIVE THAN THAT OF THE MAN
The prefrontal cortex is the heart of our learning and memorizing abilities. The prefrontal cortex is present at all stages of memorization, whether encoding, consolidation, or recall. The role of the prefrontal cortex is both to direct visual attention, to create links between the elements memorized to learn and the inhibition of information that would be distracting.
This study shows that women’s brain is significantly more active in many other regions of the brain than men, especially in the prefrontal cortex, involved in attention and impulse control, and the limbic or emotional areas of the brain , involved in mood and anxiety . The visual and coordination centers of the brain were more active in men. TEMP can measure blood perfusion in the brain. Images acquired from subjects at rest or during various cognitive tasks show different blood flows in specific regions of the brain.
The subjects included 119 healthy volunteers and 26,683 patients with various psychiatric conditions such as brain trauma, bipolar disorder, mood disorders, schizophrenia and psychotic disorders, and attention deficit disorder with or without hyperactivity (ADHD). A total of 128 brain regions were analyzed at rest and during a concentration task.
Understanding these differences is important because brain disorders affect men and women unequally. Women have much higher rates of Alzheimer’s disease, and depression, which is itself a risk factor for Alzheimer’s disease, and anxiety disorders, while men have higher rates of ADHD.
The precise definition of the physiological and structural basis of gender differences in brain function will illuminate among other things the understanding of certain pathologies such as Alzheimer’s disease and the understanding of our partners in our daily lives.
Finally, the results of this study, which show that the greater increase in blood flow of the prefrontal cortex in women compared to men, may explain why women tend to have greater forces in the areas of empathy , intuition, collaboration, or self-control.
Personally, this difference seems to me quite simple to perceive on a daily basis. Even if empathy, intuition, collaboration, and self-control are more “important” in women, these attitudes are identifiable in some male subjects – this is what I notice in the relationships I have in my daily environment here in Japan or in my friendly and professional relations in France and elsewhere. The study also found an increase in blood flow in the limbic areas of women’s brain, which may partly explain why women are more vulnerable to anxiety, depression, insomnia and lifestyle disorders. ‘food.
