hippocampal fissure

hippocampal fissure (hif)

The term hippocampal fissure (hif) refers to a deep cleft in the limbic lobe of the human ( Carpenter-1983 ), macaque ( Paxinos-2009a ), rat ( Swanson-2004 ) and mouse ( Hof-2000 ). In the primates it separates the dentate gyrus (DNG) from the CA fields (CAF), subiculum (SUB) and anterior parahippocampal gyrus (PHGa). In the rodents it separates the DNG CAF.

Also known as: hippocampal fissure (Gratiolet), hippocampal sulcus, Sulcus hippocampi, hippocampal fissure, dentate fissure, uncal sulcus

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.
