parahippocampal gyrus

parahippocampal gyrus (PHG)

The term parahippocampal gyrus refers to one of four components of the limbic lobe in the human ( Carpenter-1983 ) and the macaque ( Martin-2000 ). The other components are the cingulate gyrus, archicortex, and subcallosal gyrus. Identified by dissection, it is a prominent convolution on the mesial aspect of the cerebral hemisphere. It is separated from the fusiform gyrus of the temporal lobe laterally by the collateral sulcus and from the inferior temporal gyrus rostrally by the rhinal sulcus. It is composed of two substructures, the anterior parahippocampal gyrus (PHGa) and the posterior parahippocampal gyrus (PHGp). In Functional segmenation of the cerebral cortex the PHGp is combined with the fusiform gyrus to form the posterior parahippocampal cortex (PHCp) ( Glasser-2016 ). An equivalent structural formation is not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ). Updated 24 May 2024.

Also known as: parahippocampal gyrus, Gyrus parahippocampalis, Gyrus hippocampi, hippocampal gyrus, Gyrus parahippocampi, mesiotemporal lobe

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.
