The cingulum or fornix periphcricus is an arcuate association bundle, or rather an arcuate series of short bundles which establishes the connections of the rhinencephalon with the adjacent cortical areas (p. 955). CORTICAL LOCALIZATION OF FUNCTION. Patient researches conducted along clinicopathological, experimental, physiological, and de- velopmental lines have furnished us with a topographic map of the somesthetic and sense areas, and, inferentially, of the association areas of the cerebral cortex. The somesthetic and sense areas constitute less than one-third of the cortical area, while the remainder is presumed to be devoted to the elaboration of the higher mental activities manifested by abstract thought, ideation, reasoning, and language. The acquisition of these specifically human mental attri- butes has been the chief factor in bringing about the superior structure of the human brain, and those cortical regions which were subjected to increased associations rose in functional dignity and increased in size. With over nine billion functional nerve cells in the human cerebral cortex devoted to the mental processes, and less than one-third of these concerned with emissary and receptive functions, the intricacy and capacity of the human brain for the manifold registra- tion of sensations and the numerous transformations that characterize man's mental processes far exceed that of any other -Mesal view of left cerebral hemisphere, showing localization of functions, fissin-es and gyres is the same as in Fig. 679.
