Hippocampus is a layer of gray matter, which lies along the floor of the inferior horn of lateral ventricle. Phylogenetically, it is one of the most ancient portions of the brain.
Hippocampus receives a lot of afferent fibers, directly or indirectly related to all senses. These sensorial fibers leave the hippocampus via the fornix. Fornix, which is consisted of myelinised fibers, terminates in the thalamus, hypothalamus and septal area. This implies that there are various cycles between the hippocampus and subcortical areas. Additionally, hippocampus is in connection with a lot of distinct parts of the brain via subcortical areas. Presence of these ample connections implies that hippocampus takes place in many brain functions despite the believed restricted role only in odor, till about fifty years ago.
Limbic system, has an important role in transformation of actions to the behavioral form, and receives a great deal of signals from the hippocampus. Additionally, hippocampus has an important role in memory, especially short-term memory and it is impossible to keep verbal and symbolic memories when its functions are impaired.
While many questions are still awaiting for answers in human history, hippocampus functions represent an important subject that cannot be ignored. Perhaps, each brain component may have a function related to hippocampus.Keywords: Hippocampus, Cornu ammonisTurkiye Klinikleri J Med Sci 2001, 21:427-431
