Surgical treatment; a practical treatise on the therapy of surgical diseases for the use of practitioners and students of surgery . hidden in the central fissure, also occupiesabout the anterior half of the exposed external part of the gyrus. This is the area of com-mon sensation, cutaneous sense, tactile sense, and muscular sense. The centripetal fibersto this area pass by way of the posterior part of the internal capsule and the thalamus. The fields of special sensation lie posteriorly to and below this, where the sensationsbecome more complex and involved with association. The sensation of pain and of tempera-ture probably are located in the intermediate postcentral zone. The center for the recog-nition of objects and the stereognostic sense are situated in the parietal lobe. The visualsensory center is located in the occipital lobe especially on its mesial surface in the calcarineregion. The auditory sensations are received in the gyrus temporalis superior. _ Olfactorysensations are believed to be received in the pyriform lobe or the adjacent areas (Fig. 730). ^FISSURE OF~^Q^r-~-^_^ROLANDOLEGKNEESH^ULOEflELBOW. riSSURE OFSYLVIUS Fig. 730.—Cortical Function Topography of Brain. Craniocerebral topography determines the position of the parts of the brain with refer-ence to the exterior of the head.
