A treatise on nervous diseases; their symptoms and treatment . -temporalis medialis (lobulus lingualis); around thecentral fissure is a quadrilateral lobule, A, B, called the paracentral lobule. The accompanying representation, an outline froma photograph by Bitot, will give a sufficiently clear ideaof the more important divisions. The caudate nucleus and the outer or third memberof the lenticular nucleus receive few fibers from the co-rona radiata, nearly all of whose fibers pass into the in-ternal capsule. Fine bundles of white fibers pass fromthe lenticular nucleus into the internal capsule, andseem to pass on to the pyramidal tract. From thecaudate nucleus many bundles of fibers pass into theanterior limb of the internal capsule ; others cross thisand enter the lenticular nucleus. 22 DISEASES OF THE BRAIK The fibers which have been described as entering theinternal capsnle are destined in part for the basis ofthe cms ; the remainder are lost in the different partsof the optic thalamus, and in the tegmentum cruris,some reaching the Fig. 5.—Horizontal section of the , corpus callosum; en, caudate nucleus; fv, fifth ventricle; cl, claustrum; i,island of Eeil; cf, crura of the fornix, which, turning upon themselves, form thecorpora albicantia ; ee, external capsule; tv, third ventricle ; th, optic thalamus;cge, external corpus geniculatum; era, the lower part of caudate nucleus; pv, pul-vinar; cq. corpora quadrigemina; egi, internal corpus geniculatum; i, n, in, thethree divisions of lenticular nucleus (on the left only two divisions are seen); aic,hie, pic, the anterior limb, knee, and posterior limb of the internal capsule. The following diagrams, in some respects slightlymodified from Wernicke, will help to an understand-ing of the course of the most important bundles offibers, and the relations of the ganglia. ANATOMY. Charcot has shown that only a part of the fibers ofthe internal capsnle passes beyond the pons. The cap-sule is divided i
