The slight angle formed at the junction of the anterior and posterior rhinal fissures is the point of origin of a faint depression extending upward on the lateral surface of the cerebral hemisphere. This represents a rudiment of the lateral cerebral (Sylvian) fissure, which is a conspicuous feature in the brain of man and other mammals with convoluted Fig. 115. Dissection to show the radia- tion of the corpus callosum from a dorsal viewpoint. The longitudinal white line close to the median plane is the position of a delicate band of hippocampal fibres, the medial longitudinal stria. (d) The corpus callosum is a broad, white commissural band passing transversely between the hemispheres (Fig. 115) to connect the cortex of each with that of the other and thus providing for the co-ordination of their action. Its median portion lies at the bottom of the longitudinal cerebral fissure and may be exposed dorsally by pressing apart the medial margins of the hemispheres so as to open up the fissure. The foregoing parts belong to the telencephalon, those which follow belong to the diencephalon (p. 86). ^Though the term is sometimes loosely used, a commissure may be defined as a structure connecting corresponding parts on opposite sides. It contrasts with a decussation, which is a system of nerve-fibres crossing the median plane to connect different parts on the two Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bensley, B.
