In the main the doctrines of Gall are not without a certain foundation in facts; and the modern theory of localization of function bears a strong resemblance to what Gall taught, though with greater Temv"'^ Fig. 388.—Diagrammatic-representation of internal sm-faoe of right cerebral hemisphere, as seen in vertical longitudinal median section (af t«r Flint and Ecker). Among the more modern observers, Flourens held that re- moval of small portions of the cerebral cortex produced no effect on either will-power or intelligence, but that if carried far enough both volition and intelligence were completely de- stroyed. Later observers, say, of ten years ago, maintained that the whole or the greater part of the cerebral cortex might be mapped out into areas with a definite function. The meth- ods of investigation have been clinico-pathological and physio- logical. It was found that, on stimulating certain areas of the cortex (e. g., the so-called motor area), certain movements followed, but that similar results were obtained when the electrodes were applied directly to the white matter underlying the cortex; hence the results of such experiments were not conclusive. It was held that, if certain regions thus respondent to a stimulus were removed, the movements of corresponding muscles should V 1 1'-T,_J . ,•„ _iT J_ J-T T 1J T n„«„li^/^/1 T^OToW-.
