Sex dimorphism and more general the role of sex chromosomes on brain development may provide crucial insight into neuropsychiatric disorders as nearly all of them have different ages of onset and gender bias in prevalence. Using the XO mouse model and whole brain high resolution imaging we found characteristic differences in brain morphology comparing mice with XO, XX< and XY genotypes providing an ideal model to investigate the role of sex chromosomes in brain development across various neurodevelopmental stages and genotypes.
