...ignoramus) generally concede that he was not entirely wrong. Thanks to new brain-imaging technology, we know there are indeed real differences between the male and the female brain, more differences than we would have imagined a decade ago. "The brain is a sex organ," says Sandra Witelson, a neuroscientist who became famous in the 1990s for her study of Albert Einstein's brain. "In the last dozen years, there has been an exponential increase in the number of studies that have found differences in the brain. It's very exciting...
...yourself, "O.K., I may have a hard time with this task, but I'm going to will myself to conquer it." Some experiments show that baby girls, when faced with failure, tend to give up and cry relatively quickly, while baby boys get angry and persist, says Witelson at Ontario's Michael G. DeGroote School of Medicine at McMaster University. "What we don't know is whether that pattern persists into adulthood," she says. But in her experience in academia, she says she knows of at least a couple of brilliant women who never realized their potential in science because...
Finally, in 1996, Harvey gave much of his data and a significant fraction of the tissue itself to Dr. Sandra Witelson, a neuroscientist who maintains a "brain bank" at McMaster for comparative studies of brain structure and function. These normal, undiseased brains, willed to science by people whose intelligence had been carefully measured before death, gave Witelson a solid set of benchmarks against which to measure the seat of Einstein's brilliant thoughts. To make the comparison as valid as possible, Witelson and her team compared Einstein's tissues with those of men close...
What they found was that while the overall size of Einstein's brain was about average, a region called the inferior parietal lobe was about 15% wider than normal. "Visuospatial cognition, mathematical thought and imagery of movement," write Witelson and her co-authors, "are strongly dependent on this region." And as it happens, Einstein's impressive insights tended to come from visual images he conjured up intuitively, then translated into the language of mathematics (the theory of special relativity, for example, was triggered by his musings on what it would be like to ride through space on a beam...
...tiny gland is larger in homosexual than in straight men. But some scientists believe this structure governs daily rhythms rather than sexual behavior, so it is difficult to see any significance in the finding. Investigations of right- and left-handedness have also provided evidence of a physiological distinction. Sandra Witelson, a professor of psychiatry at McMaster University in Hamilton, Ont., has found more left-handers among homosexual women in her studies than among heterosexual women. Others have made the same observation among men. Since hand preference may be determined in part by the influence of sex hormones on the brain...
