There are high concentrations of the male sex hormone (androgen) receptors throughout the cerebral cortex in the brain‚ particularly in the visual cortex‚ which is in charge of processing images. Guys have 25% more neurons in the visual cortex than females because‚ during embryogenesis‚ androgens are responsible for controlling the development of those neurons.
