The female brain is more active than that of men



A Canadian researcher came to the conclusion that the male brain was better at rest than women. She gives his explanation Figaro.fr. Here's a study that may well awaken a few cliches ... Adrianna Mendrek Canadian researcher, Department of Psychiatry, University of Montreal and Centre de recherche Fernand-Seguin Louis-H. Lafontaine, book stuff for this: the female brain is more active than men. 

Among other banalities we often hear that men know better than women, think of nothing. This "virtue" may actually done based on a real neurological fact. At rest, the neuronal activity of the brain called "default network" effect is greater in women than in men. Does this mean that the female brain never rests? "In reality, all brains are in constant activity, meets the researcher Figaro.fr. It is a question of levels, but we can indeed say that the brains of men sits bigger and better than women. " 
"Women were in the self-evaluation" Adrianna Mendrek however cautions that "this discovery was made by chance, in a specific context, and it deserves further investigation." Specialist schizophrenia, the researcher conducting a study on patients with this disease to compare their brain activity to activity and rest, by gender. As with any clinical study, it is advisable to have a panel of healthy subjects to compare the results. Thus 42 men and not schizophrenia aged 25 to 45 women, met with a task of mental rotation from a three-dimensional figure while their brain activity was measured by magnetic resonance imaging. The same measure of neuronal activity was taken while the subjects rested between two exercises. Observation of the researcher and his team: "At rest, the women were in the self-assessment of what they had to do, and planned in what they should then realize, while men were able to completely relax. " "Social pressure" "We are not yet able to say how much a social pressure and what other have biological hormones in this difference, Adrianna Mendrek advance. In today's society, women are constantly concerned must manage multiple tasks and more things than men, so this result is it not surprising. " Measures levels of estrogen and testosterone were made during this study. Remains the team to try to establish a link with the observed activity measures, to define the exact role. And thus determine the amount of hormones and the "social pressure" "in most brain activity of women at rest. For now, the results of this study are not yet published.
