Abstract

tThe prevalence, age of onset, and symptomatology of many neuropsychiatric conditions differ betweenmales and females. To understand the causes and consequences of sex differences it is important to estab-lish where they occur in the human brain. We report the first meta-analysis of typical sex differences onglobal brain volume, a descriptive account of the breakdown of studies of each compartmental volumeby six age categories, and whole-brain voxel-wise meta-analyses on brain volume and density. Gaussian-process regression coordinate-based meta-analysis was used to examine sex differences in voxel-basedregional volume and density. On average, males have larger total brain volumes than females. Exami-nation of the breakdown of studies providing total volumes by age categories indicated a bias towardsthe 18–59 year-old category. Regional sex differences in volume and tissue density include the amyg-dala, hippocampus and insula, areas known to be implicated in sex-biased neuropsychiatric conditions.Together, these results suggest candidate regions for investigating the asymmetric effect that sex has onthe developing brain, and for understanding sex-biased neurological and psychiatric conditions.
