parahippocampal gyrus
Acronym: PHG
The term parahippocampal gyrus refers to one of four components of the limbic lobe of the cerebral cortex. The others are the cingulate gyrus, the archicortex, and the 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 four substructures. From caudal to rostral they are the posterior parahippocampal gyrus, the entorhinal area, the presubiculum and the piriform area ( Carpenter-1983 ). Functional segmenations of the cerebral cortex generally combine it with the fusiform gyrus to form the parahippocampal cortex (PHC) ( Glasser-2016 ).
     Its structure is similar in the macaque ( Martin-2000 ). Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).
