| hippocampal convolution | A long convolution on the medial surface of the temporal lobe, forming the lower part of the fornicate gyrus, extending from behind the splenium corporis callosi forward along the dentate gyrus of the hippocampus from which it is demarcated by the hippocampal fissure. The anterior extreme of the gyrus curves back upon itself, forming the uncus, the major location of the olfactory cortex. See: entorhinal area. Synonym: gyrus parahippocampalis, hippocampal convolution, hippocampal gyrus. (05 Mar 2000) |

| hippocampal fissure | A shallow groove between the dentate gyrus and the parahippocampal gyrus; the remains of a fissure extending deep into the hippocampus between Ammon's horn and the dentate gyrus which becomes obliterated during foetal development. Synonym: sulcus hippocampi, dentate fissure, fissura dentata, fissura hippocampi, hippocampal fissure. (05 Mar 2000) |

| hippocampus | <anatomy> Area of mammallian brain and an important preparation for the study of synaptic plasticity. The hippocampus has been known since the 1950s to be important for long term memory storage in humans and other mammals, it is essential for initial storing of long-term memory for a period of days to weeks before the memory trace is consolidated elsewhere. Also the site of long-term synaptic plasticity: see long-term potentiation, which is exhibited by defined synaptic pathways in the hippocampus. (18 Nov 1997) |

| hippocampus minor | The lower of two elevations on the medial wall of the posterior horn of the lateral ventricle of the brain, caused by the depth of the calcarine sulcus. Synonym: Haller's unguis, hippocampus minor, minor hippocampus, Morand's spur, unguis avis. (05 Mar 2000) |
