Immediately after the operation the animalsintelligence was very much affected, but this condition gradually passed away sothat the animal once more became very intelligent. The authors themselves andseveral other physiologists and physicians tried numerous experiments with theanimal and came to the conclusion that all its senses including hearing were per-fectly acute. Moreover, there was no chance for the claim that the reactions ofthis animal to auditory stimuli were really due to excitation of the cutaneousnerves. From these observations it appears therefore that the auditory pathwaysdo not end in the temporal lobes alone, although they may be most concentratedthere. The course of the fibers of the cochlear nerve inside the cerebrum leavesno doubt that the temporal lobes in man stand in very intimate relation with 654 PHYSIOLOGY OF THE CEREBRUM Vision. Fig. —Right cerebral hemisphere seen from the outside, after Flechsig. In this and thefollowing figure the sensory areas are indicated with red dots. The region where the dots arethickest is the region where most of the sensory pathways end. General Sensation Vision
