hippocampusnoun
A part of the brain located inside the temporal lobe, consisting mainly of grey matter. It is a component of the limbic system and plays a role in memory and emotion. So named because of its resemblance to the seahorse.

Wikipedia
Hippocampus
The hippocampus (via Latin from Greek ἱππόκαμπος, 'seahorse') is a major component of the brain of humans and other vertebrates. Humans and other mammals have two hippocampi, one in each side of the brain. The hippocampus is part of the limbic system, and plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation. The hippocampus is located in the allocortex, with neural projections into the neocortex in humans, as well as primates. The hippocampus, as the medial pallium, is a structure found in all vertebrates. In humans, it contains two main interlocking parts: the hippocampus proper (also called Ammon's horn), and the dentate gyrus.In Alzheimer's disease (and other forms of dementia), the hippocampus is one of the first regions of the brain to suffer damage; short-term memory loss and disorientation are included among the early symptoms. Damage to the hippocampus can also result from oxygen starvation (hypoxia), encephalitis, or medial temporal lobe epilepsy. People with extensive, bilateral hippocampal damage may experience anterograde amnesia: the inability to form and retain new memories. Since different neuronal cell types are neatly organized into layers in the hippocampus, it has frequently been used as a model system for studying neurophysiology. The form of neural plasticity known as long-term potentiation (LTP) was initially discovered to occur in the hippocampus and has often been studied in this structure. LTP is widely believed to be one of the main neural mechanisms by which memories are stored in the brain. In rodents as model organisms, the hippocampus has been studied extensively as part of a brain system responsible for spatial memory and navigation. Many neurons in the rat and mouse hippocampus respond as place cells: that is, they fire bursts of action potentials when the animal passes through a specific part of its environment. Hippocampal place cells interact extensively with head direction cells, whose activity acts as an inertial compass, and conjecturally with grid cells in the neighboring entorhinal cortex.

hippocampus
The hippocampus is a complex brain structure embedded deep into temporal lobe. It's a key component of the limbic system, which is involved in memory storage, learning, emotion regulation, and spatial navigation. It has a distinctive, curved shape somewhat similar to a seahorse – leading to its name, derived from the Greek words “hippos” for horse and “kampos” for sea monster. It communicates with other parts of the brain through an extensive network of neural pathways. Damage or impairments to the hippocampus can lead to a variety of memory issues, including amnesia.

Hippocampus
The hippocampus is a major component of the brains of humans and other vertebrates. It belongs to the limbic system and plays important roles in the consolidation of information from short-term memory to long-term memory and spatial navigation. Humans and other mammals have two hippocampi, one in each side of the brain. The hippocampus is a part of the cerebral cortex; and in primates it is located in the medial temporal lobe, underneath the cortical surface. It contains two main interlocking parts: Ammon's horn and the dentate gyrus. In Alzheimer's disease, the hippocampus is one of the first regions of the brain to suffer damage; memory loss and disorientation are included among the early symptoms. Damage to the hippocampus can also result from oxygen starvation, encephalitis, or medial temporal lobe epilepsy.

Hippocampus
hip′o-kam-pus, n. a genus of small fishes with head and neck somewhat like those of a horse, the sea-horse: (anat.) a raised curved trace on the floor of the lateral ventricle of the brain. [Gr. hippokampos—hippos, a horse, kampos, a sea-monster.]
U.S. National Library of Medicine
Hippocampus
A curved elevation of gray matter extending the entire length of the floor of the temporal horn of the lateral ventricle. The hippocampus, subiculum, and DENTATE GYRUS constitute the hippocampal formation. Sometimes authors include the ENTORHINAL CORTEX in the hippocampal formation.
Dictionary of Nautical Terms
hippocampus
A small fish, so termed from the head resembling that of a horse. They live among reeds and long fuci, to which they cling with prehensile tails.
