"[Among 'opposite' nineteenth-century characterizations of the functions of the two cerebral hemispheres were 'male' and 'female'.] The male hemisphere, as one writer put it in 1898, was "more intellectual,....more stable", the female "more excitable, more readily exhausted". White and non-White differences were, of course, also traceable to brain asymmetry.... Similarly, among the mad, the right, brutish side of the brain had conquered the rational left. Indeed, pathological studies revealed that the weight ratios of the hemispheres in the mad were, as one alienist discovered, "completely reversed"."
