Exploration of those parts of the brain supplied by the posterior cerebral artery
Roof of inferior horn of lateral ventricle
The hippocampal structures are now widely resected to reveal structures in the roof of the inferior horn of the ventricle. Fiber strands (15) continuing from the stria terminalis spread out across the ventricular surface of the amygdaloid nucleus (16) where it bulges downward into the inferior horn. The lateral limit of the transverse fissure is clearly seen in this specimen as the line (11) along which the choroid plexus of the ventricle is attached.
