Human males and females show profound differences in the prevalence and presentation of numerous brain-related conditions. In neurology, for example, males have a greater risk of Parkinson’s disease and tend to develop the disease earlier and with more severe cognitive impairments. Females have higher rates of multiple sclerosis, but their symptoms progress more slowly than in males. In psychiatry, all early-onset neurodevelopmental conditions are more prevalent in males than in females.

The cerebral cortex shows complex organization across diverse biological scales, from regional chemical and cellular specializations to macroscale functional networks. Zhang et al. report that macroscopic neuroimaging maps of cortical activity align with microscopic cellular features: sensory and association regions define opposing extremes for both.
