'In a sample including 5216 brains, the researchers found that even when men's larger overall brain size was taken into account, the amygdala was, on average, larger in men.

More brain differences found between the sexes. Encompassing the emotional component of sexual arousal, the amygdala has a tendency to show greater activation in men than women.' P 46 P 46-47 ' FMRI studies have indeed shown differences between men and women in amygdala when looking at visual sexual stimuli (also known as pornography). In studies using functional magnetic resonance imaging (or fMRI) which measures brain regions that 'light up' from changes in neuronal activity during a particular task, women on average outperform men on verbal fluency, (the ability to generate many different words beginning with a given letter) while men on average outperform women on mental rotation (the ability to rotate 3-dimensional geometric figures in the mind).' P 46 P 46Īnother cerebral difference between men and women on average, women and men respond differently to sexual stimuli. THESE ARE AVERAGE STATISTICS, of course in any two individuals this could be flipped. 'By this logic, men who are physically smaller would be expected to have in amygdala that is female typical, when in actuality, their amygdala would still likely resemble what is typical of men.' P 45 P 46Īn example of a cognitive difference between men and women with verbal fluency and mental rotation. Soh responding to those claiming that size difference in different/dimorphic areas of the brain can be explained away by the fact that males who have participated in these studies are physically bigger.
