According to a new study, men and women have differences in how they process visual stimuli. Men have a better sensitivity to fine detail while women are better at telling the difference between colours.
In the brain there are high concentrations of male sex hormone (androgen) receptors throughout cerebral cortex, especially in the visual cortex which is responsible for processing images. Androgens are also responsible for controlling the development of neurons in the visual cortex during embryogenesis, meaning that males have 25% more of these neurons than females.
From what I can tell the implications are…well nothing! Hooray for science! Gender!
