posterior parahippocampal gyrus (PPHG)

The term posterior parahippocampal gyrus refers to the more caudal of two parts of the parahippocampal gyrus defined by dissection of the limbic lobe in the human ( Gray-1918b ) and the macaque ( Martin-2000 ). The other part is the anterior parahippocampal gyrus. The PPHG is bounded medially by the presubiculum of the hippocampal complex and laterally by the fusiform gyrus ( Crosby-1962 ). Histologically, Brodmann-1909 classed it as perirhinal area 34; ( Economo-1927 ) as area TH, which included an internal area THa. The PPHG has no topological equivalent in the smooth cortex of the rodent and no histological equivalent to the neocortical PPHG between presubiculum and more lateral temporal area TEa in the rat are. All areas between the presubiculum in the rat are located in the entorhinal cortex and perirhinal cortex ( Swanson-1994 ). Functionally, it and the fusiform gyrus together constitute the posterior parahippocampal cortex ( Glasser-2016 ). Updated 6 Jun 2024.

Also known as: posterior parahippocampal gyrus, Gyrus parahippocampalis, pars posterior, parahippocampal gyrus (Insausti), Area Temporohippocampica, area perirhinalis, perirhinal area, area 34 of Brodmann

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.
