Pyramidal cells in the hippocampus called place cells play a significant role in self-location during movement over short distances. [3] As a rat moves along a path, individual place cells fire action potentials at an increased rate at particular positions along the path, termed "place fields".
Winged hippocamp in an Art Deco fountain, Kansas City, Missouri, (1937). The hippocampus, or hippocamp or hippokampos (plural: hippocampi or hippocamps; Ancient Greek: ἱππόκαμπος, from ἵππος, 'horse', and κάμπος, 'sea monster' [1]), sometimes called a "sea-horse" [2] in English, [citation needed] is a mythological creature mentioned in Etruscan, Greek, Phoenician, [3 ...
View of left entorhinal cortex (red) from beneath the brain, with front of brain at top. Artist's rendering. The superficial layers – layers II and III – of EC project to the dentate gyrus and hippocampus: Layer II projects primarily to dentate gyrus and hippocampal region CA3; layer III projects primarily to hippocampal region CA1 and the subiculum.
CA3a is the part of the cell band that is most distant from the dentate (and closest to CA1). CA3b is the middle part of the band nearest to the fimbria and fornix connection. CA3c is nearest to the dentate, inserting into the hilus. CA3 overall, has been considered to be the “pacemaker” of the hippocampus.
In mice, the projection to CA1, and the subiculum all come primarily from EC layer III. [citation needed]According to Suh et al. (2011 Science 334:1415) the projection to CA3 and dentate gyrus in mice is primarily from layer II of entorhinal cortex, and forms a trisynaptic path with hippocampus (dentate gyrus to CA3 to CA1), distinguished from the direct (monosynaptic) perforant path from ...
The hippocampus is located in the medial temporal lobe (subcortical), and is an infolding of the medial temporal cortex. [1] The hippocampus plays an important role in the transfer of information from short-term memory to long-term memory during encoding and retrieval stages. These stages do not need to occur successively, but are, as studies ...
Schaffer collaterals are the axons of the neurons in the CA3 regions of the hippocampus that form synapses in the CA1 regions. The hippocampus is a part of the feedback process that sends signals to stop cortisol production. Thus, a damaged hippocampus can cause memory loss and inability of cognitive function.
The hippocamp (as seen in this sketch from Pompeii) is a water creature that has been referred to as a water horse.. The term "water horse" was originally a name given to the kelpie, a creature similar to the hippocamp, which has the head, neck and mane of a normal horse, front legs like a horse, webbed feet, and a long, two-lobed, whale-like tail.
