Exploration of the brain from the medial aspect

Stria terminalis, choroidal fissure, fornix, hippocampal fissure and choroidal arteries

The optic tract and part of the lateral geniculate body have been elevated from their usual position to expose the structures in the neighborhood of the inferior horn of the lateral ventricle. These include the stria terminalis (16), choroidal fissure (18), fornix (14) and hippocampal fissure (20). Note that choroidal arteries (8, 18) are derived both from the middle cerebral and posterior cerebral arteries whereas arterial branches entering the hippocampal fissure come only from the posterior cerebral artery.
