The Geschwind Galaburda hypothesis was proposed by Norman Geschwind and Albert Galaburda to explain sex differences in cognitive abilities by relating them to Lateralization of brain function. The basic idea is that differences in maturation rates between the cerebral hemispheres are mediated by circulating testosterone levels, and that sexual maturation acts to fix the hemispheres at different relative stages of development after puberty.According to the theory, male...
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Geschwind Galaburda hypothesis was proposed by Norman Geschwind and Albert Galaburda to explain sex differences in cognitive abilities by relating them to Lateralization of brain function. The basic idea is that differences in maturation rates between the cerebral hemispheres are mediated by circulating testosterone levels, and that sexual maturation acts to fix the hemispheres at different relative stages of development after puberty.According to the theory, male brains mature later than females, and the left hemisphere matures later than the right.Although the Geschwind-Galaburda hypothesis has been cited in mainstream media and publication resources, it should be noted that very little research evidence (if any) has been presented to substantiate the theory. In fact, evidence has emerged suggesting that high prenatal estrogen exposure is more likely to enhance the gene expression for left-handedness.
