. Cunningham's Text-book of anatomy. Anatomy. 626 THE NEKVOUS SYSTEM. impressions of smell are brought into relation with those of other senses (probably taste); and from the hippocampal cells fibres are emitted to form a system known as the fornix, which establishes connexions with the hippocampus of the other hemisphere and with the hypothalamus, thalamus, and more distant parts of the brain. The rudiment of the hippocampal formation that develops on the medial surface begins in front, alongside the place where the stalk of the olfactory peduncle (which becomes the trigonum olfactorium) is inserted; it passes upwards to the superior end of the lamina terminalis, from the rest of which it is separated by a triangular mass of gray matter, the corpus paraterminale (Fig. 555); and then it proceeds back- wards, fringing the fissura chorioidea in the whole of its extent, ending below in the temporal region alongside the posterior part of the area piriformis. The an- terior part of this great hippocampal fringe of the pallium does not attain its full development in the human brain and remains as a more or less vestigial aborted Sulcus cinguli Gyrus cinguli Commissura fornicis Corpus foruicis Corpus callosun Septum pellueidum \.
