The parahippocampal gyrus (or hippocampal gyrus) is a grey matter cortical region of the brain that surrounds the hippocampus. This region plays an important role in the formation and retrieval of topographical memory. The parahippocampal place area (PPA) is a subregion of the parahippocampal gyrus that plays an important role in memory of scenes (rather than faces or objects). It first appeared in amphibians as a section of the paleopallium. Amphibians were the first vertebrates to colonize land, thus a need for terrestial navigation and memory of scenes.
