granular layer of the dentate gyrus

granular layer of the dentate gyrus (DNGgr)

The term granular layer of the dentate gyrus rrefers to the middle of three subdivisions of the fascia dentata of the dentate gyrus based on cytoarchitecture. The more superficial subdivision is the molecular layer of the dentate gyrus; the deepest is the polymorphic layer of the dentate gyrus. It is found in the human ( Insausti-2012 ), macaque ( Petrides-2009 ), rat ( Swanson-2004 ) and mouse ( Hof-2000 ). In the rat and mouse, unlike the primates, the fascia dentata has three parts: the crest of the dentate gyrus, the medial blade of the dentate gyrus and the lateral blade of the dentate gyrus. Each has a granular layer that is continuous with that of the others ( Swanson-2004 Hof-2000 ). Updated 30 May 2024.

Also known as: granular layer of dentate gyrus, granular layer of the dentate gyrus, granular cell layer, Stratum granulosum, granule cell layer, dentate gyrus, granular layer, Stratum granulare

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.
