What does the hippocampus represent?
hippocampus, region of the brain that is associated primarily with memory. The name hippocampus is derived from the Greek hippokampus (hippos, meaning “horse,” and kampos, meaning “sea monster”), since the structure’s shape resembles that of a sea horse.
What is nucleus Reuniens?
The nucleus reuniens (RE) is a ventral midline thalamic nucleus that interconnects the medial prefrontal cortex (mPFC) and hippocampus (HPC).
Is Ammon’s horn the hippocampus?
The hippocampus is also called Ammon’s Horn because the two hippocampi bend around in the form of the horns of a ram. Schematic drawing showing the major and surrounding structures of the limbic system.
Is hippocampus a nucleus?
Its projecting pathways include the medial septal nucleus and supramammillary nucleus. The dorsal hippocampus also has more place cells than both the ventral and intermediate hippocampal regions. The intermediate hippocampus has overlapping characteristics with both the ventral and dorsal hippocampus.
What is a hippocampus mythical creature?
HIPPOKAMPOI (Hippocamps) were the fish-tailed horses of the sea. They were depicted as composite creatures with the head and fore-parts of a horse and the serpentine-tail of a fish.
Which nucleus of the thalamus has projections with the hippocampus?
The nucleus reuniens (RE) of the ventral midline thalamus is the largest of the midline thalamic nuclei and has been established as the major source of thalamic input to the hippocampus (Herkenham, 1978; Wouterlood et al., 1990; Bokor et al., 2002).
Do we have 2 hippocampus?
Because the brain is lateralized and symmetrical, you actually have two hippocampi. They are located just above each ear and about an inch-and-a-half inside your head.
Who named the hippocampus?
Julius Caesar Arantius
Julius Caesar Arantius is one of the pioneer anatomists and surgeons of the 16th century who discovered the different anatomical structures of the human body. One of his prominent discoveries is the hippocampus.
What is a hippogriff in Greek mythology?
hippogriff, a legendary animal that has the foreparts of a winged griffin and the body and hindquarters of a horse. The creature was invented by Ludovico Ariosto in his Orlando furioso and was based on a proverbial phrase about crossing a griffin with a horse that was used to signify an impossibility or incongruity.

What is the nucleus reuniens?
The nucleus reuniens is a component of the thalamic midline nuclear group. In the human brain, it is located in the interthalamic adhesion ( massa intermedia ).
Does the thalamic nucleus reuniens mediate interactions between the hippocampus and cortex?
“Role of the thalamic nucleus reuniens in mediating interactions between the hippocampus and medial prefrontal cortex during spatial working memory”. Frontiers in Systems Neuroscience. 9: 29. doi: 10.3389/fnsys.2015.00029.
What is the mythic hippocampus?
The mythic hippocampus has been used as a heraldic charge, particularly since the Renaissance, most often in the armorial bearings of people and places with maritime associations.
Where does the nucleus reuniens receive afferent input?
The nucleus reuniens receives afferent input from a large number of structures, mainly from limbic and limbic-associated structures. It sends projections to the medial prefrontal cortex, the hippocampus, and the entorhinal cortex, although there exist sparse connections to many of the afferent structures as well.
