Exploration of those parts of the brain supplied by the posterior cerebral artery

Close-up view of dentate fascia and hippocampus from their internal aspects

In this view considerable detail of the organization of fiber bundles in the depths of the fascia dentata (5) can be observed. The surface of the fascia dentata exposed here is that which faces the hippocampal gyrus across the cleavage line formed at the hippocampal fissure. Small straight arterial branches of the choroidal vessels derived from the posterior cerebral artery enter the tissue along the line of the fissure and pass inward between the fiber bundles. The curved molecular layer in the depths of the hippocampus (13) is seen to be in continuity with the tooth-like radiations of fibers of the dentate fascia. The alveus (12), which forms the smooth convex ventricular surface of the hippocampus as it is usually seen, is here viewed from its internal or attached aspect.
