The hippocampus is a structure in the brain that has been associated with various memory functions. It is part of the limbic system, and lies next to the medial temporal lobe. It is made up of two structures, the Ammon's Horn, and the Dentate gyrus, each containing different types of cells. [1]
Humans have two hippocampi, one in each hemisphere of the brain.They are located in the medial temporal lobe of the brain. In this lateral view of the human brain, the frontal lobe is at the left, the occipital lobe at the right, and the temporal and parietal lobes have largely been removed to reveal one of the hippocampi underneath.
It is the most evolutionarily advanced part of the brain. [67] Greater surface area of the brain is linked to higher intelligence as is the thicker cortex but there is an inverse relationship—the thicker the cortex, the more difficult it is for it to fold. In adult humans, thicker cerebral cortex has been linked to higher intelligence. [67]
The axolotl is less commonly used than other vertebrates, but is still a classical model for examining regeneration and neurogenesis. Though the axolotl has made its place in biomedical research in terms of limb regeneration, [19] [20] the model organism has displayed a robust ability to generate new neurons following damage.
Despite the reduced brain matter, the man lived a relatively normal life; he was a married civil servant with two kids. He also scored an IQ of 75 which is considered low but not disabled.
Hippocampus anatomy describes the physical aspects and properties of the hippocampus, a neural structure in the medial temporal lobe of each cerebral hemisphere of the brain. It has a distinctive, curved shape that has been likened to the sea-horse creature of Greek mythology, and the ram's horns of Amun in Egyptian mythology.
Embryonic vertebrate subdivisions of the developing human brain hindbrain or rhombencephalon is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla , pons , and cerebellum .
In the case of drug-induced amnesia, it may be short-lived and patients can recover from it. In another case, which has been studied extensively since the early 1970s, patients often have permanent damage, although some recovery is possible, depending on the nature of the pathophysiology. Usually, some capacity for learning remains, although it ...
