Gender Differences in the Brain

NeuronsMales have larger neurons than females, but females' neurons are packed more densely together. Also, men tend to use their grey matter when thinking, which is made up of active neurons, whereas women tend to use their white matter, which consists primarily of the connections between neuons.

Corpus CallosumFemales have a corpus callosum that is 23% thicker than males, providing the female brain with more synapses between the two hemispheres. This has shown to be related to articulateness and fluency in language

Cerebral CortexMales have a thicker right cerebral cortex, while females have a thicker left cerebral cortex

HypothamalusIn male rats, the hypothalamus is visibly larger than the hypothalamus in female rats. In males, the hypothalamus works on the principle of negative feedback to maintain constancy. In females, the hypothalamus works on the principle of positive feedback to increase fluctuation in the system. (The highs get higher, the lows get lower, resulting in more emotionality)

AmygdalaThe Amygdala tends to be larger in males. Research has shown that when shown violent films, women display greater activity in the amygdala on the left hemisphere, while it was the opposite for men. Men had a difficult time remembering information crucial to the story, while women had a difficult time recalling peripheral details one week later. Long story short, this may be why men tend to recall the gist of en emotional event, while women tend to remember specific details.

HippocampusIn women, studies have shown the hippocampus to be larger than in men.This could be an indication of longer-lasting memories, and a different way of interpreting spatial memory.
