The parahippocampal gyrus (or hippocampal gyrus [1]) is a grey matter cortical region of the brain that surrounds the hippocampus and is part of the limbic system. The region plays an important role in memory encoding and retrieval. It has been involved in some cases of hippocampal sclerosis. [2] Asymmetry has been observed in schizophrenia. [3]
The uncus is an anterior extremity of the parahippocampal gyrus.It is separated from the apex of the temporal lobe by a sulcus called the rhinal sulcus. [1] Although superficially continuous with the hippocampal gyrus, the uncus forms morphologically a part of the rhinencephalon.
Brodmann area 27 is a cytoarchitecturally defined cortical area that is a rostral part of the parahippocampal gyrus.It is commonly regarded as a synonym of presubiculum. [1] ...
Anatomical terms of neuroanatomy [ edit on Wikidata ] The cingulate gyrus commences below the rostrum of the corpus callosum , curves around in front of the genu , extends along the upper surface of the body, and finally turns downward behind the splenium , where it is connected by a narrow isthmus with the parahippocampal gyrus .
The hippocampal subfields are four subfields CA1, CA2, CA3, and CA4 that make up the structure of the hippocampus.Regions described in the hippocampus are the head, body, and tail, and other hippocampal subfields include the dentate gyrus, the presubiculum, and the subiculum.
The EC is located in the parahippocampal gyrus, a cortical region adjacent to the hippocampus. [30] This gyrus conceals the hippocampus. The parahippocampal gyrus is adjacent to the perirhinal cortex, which plays an important role in the visual recognition of complex objects. There is also substantial evidence that it makes a contribution to ...
