Sex differences are more prominent than age differences in prefrontal cortex. a Principal component analysis (PCA) of pre-frontal cortex gene expression data shows a separation between female (red) and male (blue). Pooled samples of both sexes are located in the middle between male and female. Sex-specific clustering gives heterogeneous images of age groups where only tendencies for clusters of younger samples to the left and more older samples to the right can be identified in male (b) as well as female (c). d The dendrogram of male and female samples together shows large sex-specific contiguous regions
