NIH study shows highly reproducible sex differences in aspects of human brain anatomy

(NIH/National Institute of Mental Health) A scientific analysis of more than 2,000 brain scans found evidence for highly reproducible sex differences in the volume of certain regions in the human brain. This pattern of sex-based differences in brain volume corresponds with patterns of sex-chromosome gene expression observed in postmortem samples from the brain's cortex, suggesting that sex chromosomes may play a role in the development or maintenance of sex differences in brain anatomy.
