hilus of the dentate gyrus

hilus of the dentate gyrus (HDG)

The term hilus of the dentate gyrus refers to one of two parts of the dentate gyrus identified by topology in the human ( Insausti-2012 ) and macaque ( Paxinos-2009a ). It is the stem of the dentate gyrus, whicht attaches it to the CA fields in the functionally defined hippocampal complex. The body of the gyrus is the fascia dentata. The hilus is commonly referred to by the name of its domininant cell group, the CA4 field ( Paxinos-2009a ). Updated 30 May 2024.

Also known as: hilus of the dentate gyrus, Hilus gyri dentati, field CA4 of hippocampal formation, Region IV of hippocampus proper, Region CA4, field CA4 of the hippocampus, Hilus fasciae dentatae

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.
