Dr. Sandra Witelson

Sandra Witelson, Professor of Psychiatry at McMaster University, has an international reputation for the scientific study of brain-behaviour relations. She has established a unique bank of human brains for which there are prospective neuropsychological data, and has discovered that there are both sex and handedness differences in the morphology of the corpus callosum and the temporal cortex. She has developed techniques for assessing functional cerebral asymmetries through tactual stimulation, and has related these to language disorders. Her interests in sexual differentiation have also led to research on the neurobiology of sexual preference, and to major contributions in developmental neurobiology.
