Men's Brain Vs. Women's Brain

Understanding The Human Brain
(1996) Children’s Britannica, Jennifer Cox, Ed., Encyclopedia Britannica, Inc. 136-141.

The brain is the source of all our behaviour, thoughts, feelings, and experiences. We have known for a long time that different areas of the brain are used for different activities - memory, language, problem-solving, and so on. Doreen Kimura, professor of psychology at the University of Western Ontario, explains how the latest studies also show that, although all human brains are very similar, there are small differences in the way the brain is organized between one person and another. These differences may underlie some of our unique talents.

Male and female brains
Whether you are a boy or a girl also determines how your brain looks and works. We know from animal research that substances called sex hormones, produced by the sex glands, are needed to develop the differences between males and females. Sex hormones are necessary both for forming the genitals and for the behavioural and brain differences between the sexes. The hypothalamus, which is a tiny structure at the base of the brain, regulates many basic functions, such as eating, sleeping, temperature control, and reproduction. One part of the hypothalamus responsible for sexual behaviour is larger in male brains than in female brains, in human and non-human animals. In rats the enlargement is known to depend on male sex hormones, called androgens.
Sex hormones also affect other parts of the brain. For example, the outer layer of the cerebrum, called the cortex, is thicker on the right hemisphere than on the left in male rats, but not in female rats. Another recent discovery is that male and female brains in some ways work differently. When set the same task, females may use both hemispheres, while male brain activity is restricted to one side. For example, if the task is to define words, men appear to use only their left hemisphere, while women use both. For many other problem-solving activities however, men's and women's brains work in the same way.
The left and right cerebral hemispheres are connected by fibres running crosswise between them called commissures. The largest and most important commissure is called the corpus callosum; another important connection is the anterior commissure. One way the commissures are useful is in exchanging information between the two hemispheres.
These connections between the hemispheres may also be somewhat different in men and women. The area of the anterior commissure seems to be larger in women, and some researchers have found that the back part of the corpus callosum is larger in women. If the larger area of the commissures results in better communication between hemispheres, this could make some difference to the way men's and women's brains work.
Finally, there is probably also a difference between men and women as to which part of the left hemisphere is responsible for speech and hand movements. There are two major areas devoted to speech, one in the frontal lobe, and the other at the back, where the temporal and parietal lobes meet. In women, the frontal region is more important than the area at the back, so problems with speaking are more likely to happen if the front part of the left hemisphere is damaged. In men, the areas contribute more equally, but if anything the back part, especially the parietal region, is more important.
