Nervous and mental diseases . ally and the caudate nucleus and the optic thalamus on itsmedian aspect, but is not dependent upon them. Its anterior portion,or limb, is supposed to contain psychic paths to the frontal of this part of the internal capsule produce no distinctivesymptoms. The motor routes lower down are continued in the underportion of the crura and so on through the pons into the medulla andcord. The motor paths and their relations are indicated in figure 77,,which shows that the face mechanism is inferiorly situated in the cortex,anteriorly in the capsule, and internally in the cms. The sensory paths, situated in the posterior columns of the cord, passupward into the posterior third of the hinder limb of the internal cap-^sule. They reach the cortex of both hemispheres, according to Brissaud CEREBRAL WHITE MATTER, BASAL GANGLIA, CEREBELLUM. 185 and others, directly on the same side and indirectly on the opposite side,by sending off a branching path through the corpus callosum, as shown.
