The male neocortex is 20% bigger than female. This is mammalian distinguising feature and is responsible for numerous higher brain functions.

The corpus collosum is wider in females and longer in males.

IQ tests show men higher. 4 IQ points may not seem significant, but considering it is not a linear scale is it more than “very similar”. Female IQ ranges hover around the median, whereas male IQ has more variance: There are more male geniuses and more male idiots than females.

Of course something twice as big contains twice as many cells.

Cerebral lateralization does occur in right handed people and 70% of left handed people. Female have greater Werniche’s and Broca’s areas(language) and males have larger Parietal lobes(spatial reasoning)

The front lobe is somewhat similar in both. The limbic system activity is based on the individual’s activity.

Actually, if you have fewer cells, you do use them less. You have fewer cells used.

Networked cells can be effective, but it is shown that an overly networked cellular structure becomes clogged and inefficient. The neuroplasticity of the organ can correct this.

GTFO woman.

Women have slightly smaller brains than men (they weigh about 4oz/100g less) but, as we know, size isn’t everything. Elephants, for instance, have much larger brains than humans, but nobody believes they have more intellect. And though women’s brains are smaller than men’s, they both have a very similar ratio of brain weight to body weight.

Women also have 4 per cent fewer brain cells than men, but this doesn’t mean they use them less.

The frontal lobe of the brain plays a major part in making judgements, planning future actions, and in language. Women have far more cells here than men.

It is believed that these two halves of the brain probably work differently. The left side helps us think analytically, while the right side helps us look at things as a whole, involving value judgements and emotion. Men are more likely to be “left-brain dominant” while women are thought to use both hemispheres more equally.

The corpus callosum transfers information between both halves of the brain. Women have a bigger corpus callosum than men, which may account for the fact that women score better on tests of thought fluency and speech.

Processing information goes on in the grey matter, while white matter connects the different parts of our brain, enabling us to carry out various tasks. Women tend to have far more white matter than men, while men are endowed with far more grey matter. Could any or all of these differences above be an explanation for the popular theory that women are better at “multitasking” than men?

The hypothalamus controls the endocrine system that produces many of the hormones in the body. The functions it regulates include sexual function, sleep, water content, and body temperature. In men the hypothalamus is about twice as big and contains twice as many cells as it does in women.

Despite the physical differences between the male and female brain, there seems to be little, if any, difference between them as far as overall intelligence is concerned. The average IQ (intelligence quotient) score for men and for women is very similar, but that doesn’t mean we’re all the same. In fact, far more men than women get very high or very low scores.

That means there are probably more very clever men around than there are very clever women, but there are also more men than women at the bottom of the class.

Ever heard of test tube babies?
