Study unveils differences in men, women’s neural wiring

Posted by  on Dec 4th, 2013 /


A study has identified remarkable differences in the neural wiring of men and women that clarifies why males and females have different abilities at certain tasks.

The study carried out at the University of Pennsylvania through observing the connectomes (a comprehensive mapof neural connections in the brain) of both sexes revealed greater neural connectivity from front to back and within one hemisphere in males.

The scanned brains of nearly 1000 men, women, boys and girls helped the team unveil the differences, according to the study report published in journal Proceedings of the National Academy of Sciences (PNAS).

According to the recent observation, the researchers suggest male brains are structured to facilitate connectivitybetween perception and coordinated action.

They also say that Brain’s wiring map in women goes between the left and right hemispheres, indicating that “they facilitate communication between the analytical and intuition.”

The findings explain “why men, in general, tend to be better at learning and performing a single task, like cycling or navigating, whereas women are more equipped for multitasking,” researchers say.

The team analyzed the brains by using diffusion tensor imaging (DTI) which is a water-based imaging technique that can trace and highlight the fiber pathways connecting the different regions of the brain.

“Detailed connectome maps of the brain will not only help us better understand the differences between how men and women think, but it will also give us more insight into the roots of neurological disorders, which are often sex related,” said one of the researchers Doctor Ruben Gur.

The research was conducted by Ragini Verma, an associate professor in the department of Radiology at the Perelman School of Medicine at the University of Pennsylvania and her colleagues.
