Scientists have known for a while now that men and women have slightly different brains, but for many years they thought the changes were limited to the hypothalamus -- the part of your brain that controls sex drive and food intake.
Referring to the Scientific American "Sex Differences in the Brain" by Doreen Kimura, “The area in the brain that regulates female and male reproductive behavior is the hypothalamus. In 2001, researchers found that certain parts of the brain were differently sized in males and females. The study found that parts of the frontal lobe, responsible for problem-solving and decision-making, and the limbic cortex, responsible for regulating emotions, were larger in women. In men, the parietal cortex, which is involved in space perception, and the amydala, which regulates sexual and social behavior, were larger in men.
Scientists have also found parallel sex differences in a clump of nerve cells in the human brain–parts of the interstitial nucleus of the anterior hypothalamus–that is larger in men than in women. Even sexual orientation and gender identity have been related to anatomical variation in the hypothalamus. These findings are consistent with suggestions that sexual orientation and gender identity have a significant biological component.
So, what does this all mean? Well, seeing as how scientists are highly trusted figures in society, people will believe them when they release information about important topics such as sex. When people believe something, such as the sexual differences in the male and female brains because the person who relayed that information was highly credible, it is called an ethos appeal in rhetoric.
