Sexueller Dimorphismus des menschlichen Gehirns - eine Literaturübersicht

: Some findings of neurobiological brain research regarding structural sex differences of the human brain are reviewed and discussed. Besides the well known difference in brain size, especially some cell groups of the hypothalamus display differences between the sexes. The results obtained for other regions, such as the corpus callosum and other commissural systems, are inconclusive. Further dimorphisms involve the temporal lobes and sex-specific brain asymmetry. These differences seem to be subtle and are superimposed by high interindividual variability. Finally, little morphological support is found for behavioural differences between the sexes.
