Women' s minds work differently from men' s. At least, that is what most men are convinced of. Psychologistsview the subject either as a matter or frustration or a joke. Now the biologists have moved into this minefield, andsome of them have found that there are real differences between the brains of men and women. But being different,they point out hurriedly, is not the same as being better or worse.
There is, however, a definite structural variation between the male and female brain. The difference is in a partof the brain that is used in the most complex intellectual processes--the link between the two halves of the brain.
The two halves are linked by a trunkline of between 200 and 300 million nerves, the corpus callosum. Scientistshave found quite recently that the corpus callosum in women is always larger and probably richer in nerve fibers thanit is in men. This is the first time that a structural difference has been found between the brains of women and menand it must have some significance. The question is "What?", and, if this difference exists, are there others? Re-search shows that present-day women think differently and behave differently from men. Are some of these differ-ences biological and inborn, a result of evolution? We tend to think that is the influence of society that producesthese differences. But could we be wrong?
Research showed that these two halves of the brain had different functions, and that the corpus callosum enabledthem to work together. For most people, the left half is used for wordhanding, analytical and logical activities; theright half works on pictures, patterns and forms. We need both halves working together. And the better the connec-tions, the more harmoniously the two halves work. And, according to research findings, women have the betterconnections.
But it isn' t all that easy to explain the actual differences between skills of men and women on this basis. Inschools throughout the world girls tend to be better than boys at "language subjects" and boys better at maths andphysics. If these differences correspond with the differences in the hemispheric trunkline, there is an unalterable dis-tinction between the sexes.
We shan' t know for a while, partly because we don' t know of any precise relationship between abilities inschool subject and the functioning of the two halves of the brain, and we cannot understand how the two halves inter-act via the corpus callosum. But this striking difference must have some effect and, because the difference is in theparts of the brain involved in intellect, we should be looking for differencesin intellectual processing.
