(After Toldt.) ganglia of the middle brain and inter-brain. These fibers, which pass intothe cortex of the parietal lobe, probably extend to the same region where themotor centers are also found. According to Ramon they there encircle thesmall pyramidal cells of the cortex. Doubtless these combinations formother cortical territories which are as yet unknown. The fibers of the optic nerve follow another path. Like the optic radia- 100 HISTOLOGY OF THE CENTRAL NERVOUS SYSTEM tion, they run backward from the posterior capsule into the occipital lobes(Fig. 82). All of the auditory filers appear to reach the temporal lobes andto distribute themselves through its cortex (Fig. 79).
