Women’s mindswork differently from men’s. At least, that is what most men are convinced of.Psychologists view the subject either as a matter or frustration or a joke. Nowthe biologists have moved into this minefield, and some of them have found thatthere are real differences between the brains of men and women. But beingdifferent, they point out hurriedly, is not the same as being better or worse. There is, however, adefinite structural variation between the male and female brain. The differenceis in a part of the brain that is used in the most complex intellectualprocesses-the link between the two halves of the brain. The two halves arelinked by a trunkline of between 200 and 300 million nerves, the corpuscallosum. Scientists have found quite recently that the corpus callosum inwomen is always larger and probably richer in nerve fibres than it is in men.This is the first time that a structural difference has been found between thebrains of women and men and it must have some significance. The question is “What?”,and, if this difference exists, are there others? Research shows thatpresent-day women think differently and behave differently from men. Are someof these differences biological and inborn, a result of evolution? We tend tothink that is the influence of society that produces these differences. Butcould we be wrong? Research showed thatthese two halves of the brain had different functions, and that the corpuscallosum enabled them to work together. For most people, the left half is usedfor wordhanding, analytical and logical activities; the right half works onpictures, patterns and forms. We need both halves working together. And thebetter the connections, the more harmoniously the two halves work. And, accordingto research findings, women have the better connections. But it isn’t all thateasy to explain the actual differences between skills of men and women on thisbasis. In schools throughout the world girls tend to be better than boys at “languagesubjects”and boys better at maths and physics. If 〖 WTHZ 〗 thesedifferences 〖 WTBZ 〗 correspondwith the differences in the hemispheric trunkline,there is an unalterabledistinction between the sexes. We shan’tknow for a while,partly because we don’t know of any precise relationshipbetween abilities in school subject and the functioning of the two halves ofthe brain, and we cannot understand how the two halves interact via the corpuscallosum. But this striking difference must have some effect and, because the differenceis in the parts of the brain involved in intellect, we should be looking fordifferences in intellectual processing. 1.
