As for size, the
male brain is 10% to 15% larger than the female brain. As for overall weight,
the average weight of male's brain weighs 11-12% more than the average female's
brain. Other differences between male and female brains are certain structural
differences, which researchers believe may help balance out the overall size
differences between males and females. Studies have shown that parts of the
frontal lobe, which are responsible for decision-making and problem-solving,
and the limbic cortex, which are responsible for regulating emotions, are
larger in the brains of women (Edmonds, 2013). In the brains of men the parietal
cortex, that is involved in space perception, and the amygdala, that regulates
social and sexual behavior are larger (Edmonds, 2013). The male brain have
approximately 6.5 times more gray matter than the brain of a female, but the
female brain has nearly 10 times more white matter than the brain of male
(Edmonds, 2013).
Another
difference is that in the brains of a female, neurons are packed in tighter
(closer together) than in the brains of a male. Edmonds (2013), "this
proximity, in conjunction with speedy connections facilitated by the white
matter, is another reason why women's brains work faster" (para. 4). In
some female's brains on certain layers of the cortex, there may be as many 12
percent more neurons (responsible for signals coming in and out of the brain)
than in the brain of a male (Edmonds, 2013). Although, this does not predict
intelligence or IQ scores, which scientists have determined by conducting
imaging studies on how women and men think. Further research may determine more
differences between male and female brains.
