The corpus striatum projects upwards into each lateral ven- tricle, and gives to this a somewhat semilunar form, the two horns of which constitute the permanent anterior and descending comua of the lateral ventricles (Fig. 126 St). With the further growth of the hemisphere the cor- pus striatum loses its primitive relations to the de- scending cornu. The reduction in size of the foramen of Monro above mentioned is, to a large extent, caused by the growth of the corpora striata. The corpora striata are united at their posterior border with the optic thalami. In the later stages of development the area of contact between these two pairs of ganglia increases to a large extent (Fig. ].25),.
