How Men's Brains Are Wired Differently Than Women's Men aren't from Mars and women aren't from Venus, but their brains really are wired differently, a new study suggests. The research, which involved imaging the brains of nearly 1,000 adolescents, found that male brains had more connections within hemispheres, whereas female brains were more connected between hemispheres. The results, which apply to the population as a whole and not individuals, suggest that male brains may be optimized for motor skills, and female brains may be optimized for combining analytical and intuitive thinking. "On average, men connect front to back [parts of the brain] more strongly than women," whereas "women have stronger connections left to right," said study leader Ragini Verma, an associate professor of radiology at the University of Pennsylvania medical school. Previous studies have found behavioral differences between men and women. Currently, scientists can't quantify how much an individual has male- or female-like patterns of brain connectivity.

Brain Connectivity Study Reveals Striking Differences Between Men and Women PHILADELPHIA — A new brain connectivity study from Penn Medicine published today in the Proceedings of the National Academy of Sciences found striking differences in the neural wiring of men and women that’s lending credence to some commonly-held beliefs about their behavior. In one of the largest studies looking at the “connectomes” of the sexes, Ragini Verma, PhD, an associate professor in the department of Radiology at the Perelman School of Medicine at the University of Pennsylvania, and colleagues found greater neural connectivity from front to back and within one hemisphere in males, suggesting their brains are structured to facilitate connectivity between perception and coordinated action. In contrast, in females, the wiring goes between the left and right hemispheres, suggesting that they facilitate communication between the analytical and intuition. In the study, Verma and colleagues, including co-authors Ruben C.
