choroidal fissure - BrainInfo

choroidal fissure (chf)

The term choroidal fissure refers to a cleft-like opening in the wall of the lateral ventricle that appears when the choroid plexus is dissected away. It extends from the interventricular foramen to the end of the temporal horn of the lateral ventricle. The part nearest the interventricular foramen is between the lateral edge of the fornix and the upper surface of the thalamus; in the inferior horn it is between the fimbria and the stria terminalis ( Gray-1918a ).

Also known as: choroidal fissure, Fissura choroidea, choroid fissure, chorioid fissure, fissura chorioidea

Models Where It Appears

Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.
