Women Have More Active Brains Than Men
Results of a survey of 46,034 brain imaging studies


This side view of the brain summarizes blood flow results from tens of thousands of study subjects showing increased blood flow in women compared to men. Women had higher blood flow in the red colored areas of the brain (cingulate gyrus and precuneus). Men had higher blood flow in the blue colored area (cerebellum).

Scientists have just published the results of a survey of 46,034 brain imaging studies meant to understand gender-based risk for brain disorders. Analyzing such a large sample of brain scans allowed researchers to identify gender differences in brain activity. The research paper states: "The brains of women in the study were significantly more active in many more areas of the brain than men, especially in the prefrontal cortex, involved with focus and impulse control, and the limbic or emotional areas of the brain, involved with mood and anxiety. The visual and coordination centers of the brain were more active in men."
