Surgical anatomy : a treatise on human anatomy in its application to the practice of medicine and surgery . r of the hemisphere of the cerebrum, innnediatelybehind the commencement of the fissure of Rolando. From the point where thefissure turns upward to reach the margin of the hemisphere there is frequentlyfound, following the original direction of the calloso-marginal, a small fissurewhich separates the quadrate lobule from the gyrus fornicatus. This, under thename of the subparietal fissure, is a branch of the calloso-marginal, as is also theparacentral fissure. The calloso-maiginal fissure is not infrequently bridged overin places by secondary convolutions which connect the marginal gyrus with thegyrus fornicatus. The callosal fissure, or ventricle of the corpus callosum, commences belowthe rostrum, follows the superior surface of the corpus callosum, and terminatesbehind the splenium of the corpus callosum in the hippocampal fissure.

It commences in front of the anterior jjerforated space, between therostrum of the corpus callosum and the marginal convolution, follows the super-ficial surface of the corpus callosum, and terminates below the splenium of thecorpus callosum in a narrow extremity, the isthmus, which joins the hippocampalconvolution. The Limbic Lobe includes a number of convolutions arranged in a ring-likemanner; some of the parts are quite rudimentary in the human brain, and are therepresentatives of more
