Fig. 62 Section at the level of the neuroporic recess showing how the primor-dium hippocampi becomes the bed of the hippocampal commissure. On the leftside where the cells are drawn, all the white space is filled by commissural fibers. Fig. 63 Rat, parasagittal section near the median plane. The hippocampalflexure and the upper end of the facia dentiata are cut. The section cuts length-wise of the fornix superior where that pushes between the hippocampal com-missure and the corpus callo
