The story

An analysis of 949 brain scans shows significant sex differences in the connections between different brain areas.

What they actually did

Researchers from Philadelphia took data from 949 brain scans and divided them into three age groups and by gender. They then analysed the connections between 95 separate divisions of each brain using a technique called Diffusion Tensor Imaging.

With this data they constructed “connectome” maps, which show the network of the strength of connection between those brain regions.

Statistical testing of this showed significant differences between these networks according to sex — the average men’s network was more connected within each side of the brain, and the average women’s network was better connected between the two hemispheres. These differences emerged most strongly after the age of 13 (so weren’t as striking for the youngest group they tested).
