The human brain. Differences in male and female brain size are relative to body size. [83] Early research into the differences between male and female brains showed that male brains are, on average, larger than female brains. This research was frequently cited to support the assertion that women are less intelligent than men.
The human brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous ...
It was found that the group of men slightly outperformed the women in both the verbal-numerical reasoning and reaction time tests. Subsequently, the researchers tested to what extent the differences in performance was mediated by the varying attributes of the male and female brain (e.g. surface area) using two mixed sample groups.
A 2004 study published in the journal of Applied Cognitive Psychology found significantly higher male performance on four visuo-spatial working memory. [4] Another 2010 study published in the journal Brain and Cognition found a male advantage in spatial and object working memory on an n-back test but not for verbal working memory. [5]
The brain and central nervous system reside in an area protected from the rest of the body by the blood brain barrier. The lungs sit in the pleural cavity. The intestines, liver, and spleen sit in the abdominal cavity. Height, weight, shape and other body proportions vary individually and with age and sex.
The cerebral cortex is the part of the brain that most strongly distinguishes mammals. In non-mammalian vertebrates, the surface of the cerebrum is lined with a comparatively simple three-layered structure called the pallium. In mammals, the pallium evolves into a complex six-layered structure called neocortex or isocortex. [62]

The front commission was found to be wider in homosexual men than heterosexual men, and the corpus callosum was found to be larger in homosexual men than heterosexual men. [9] Some areas of the brain which researchers looked at but did not find differences in structure between sexualities are the temporal cortex, hippocampus and putamen. [9]
