BASAL GANGLIA OF THE CEEEBEAL HEMISPHEEE. 637 Hippocampus Trigonum collaterale Posterior horn of lateral ventricle Calcar avis Bulb of the cornu stood that the arcuate chorioid fissure, throughout its whole length (viz., from the interventricular foramen to the extremity of the inferior horn of the lateral ventricle), is formed by the involution of the roof and a portion of the wall of the hemisphere which remains epithelial. In the central part of the ventricle this layer is attached, on the one hand, to the sharp lateral margin of the fornix, and on the other to the superior surface of the thalamus; in the inferior horn it is attached, in like manner, to the edge of the fimbria hip- pocampi or crus of the fornix, whilst above it joins the roof of this portion of the ventricle along the line of the stria terminalis (Fig. 564). The eminentia collateralis shows very great differences in its degree of development. The trigonum collaterale is a smooth elevation in the floor of the ventricle, in the interval which is left between the calcar avis and the hippo- campus as they diverge one from the other.

Fimbria hippocampi, gray matter more or less com- pletely embedded in the white medullary substance of the hemisphere, and which are developed in its wall. They compose the caudate and lentiform nuclei, which together form the corpus striatum, and the amygdaloid nucleus. The nucleus caudatus bulges into the lateral ventricle. It is a piriform, highly arched mass of gray matter, which presents a thick, swollen head, or anterior extremity, and a long, attenuated tail. The head projects into the anterior horn of the lateral ventricle, whilst its narrower part is prolonged latera
