This review is centered on anatomical sex differences in neuronal organization in parts of
the rat nervous system that are associated with “cognitive” rather than reproductive function …

The sexual dimorphism of the corpus callosum has remained controversial since the original
report by de Lacoste-Utamsing and Holloway in 1982, for several reasons:(1) …

Neuroanatomical sex differences were observed in the midsagittal area of both the anterior
commissure and the massa intermedia on analysis of postmortem tissue from 100 age …

In view of conflicting data in the existing literature, we examined 53 normal subjects using a
handedness questionnaire and callosal area measurements obtained from midsagittal MRI …

The rat's corpus callosum is sexually dimorphic with the male's being larger. This difference
appears to depend in part on the neonatal presence of testosterone in the male and ovarian …

Dendritic spines from the apical shaft of layer V pyramids were counted on Golgi-stained
sections of the monocular subfield of the primary visual cortex of 10-, 20-, 40-and 60-day-old …

Previous research found that the corpus callosum of male rats is larger than that of females;
handling rats in infancy enhances this sex difference; and female rat pups, when handled in …

Anatomical sex differences were examined in the cortex of socially housed Long-Evans
hooded rats at 90 days of age. Sex differences in cortical size were found to be widespread …

In laboratory animals, gonadal hormones act upon the brain during the perinatal period of
development to sexually differentiate both its structure and function. In contrast, in humans …
