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 [1] [2] [3] as well as other primates. [4]
The hippocampus. 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]
A key physiological function of the CA3 is encoding heteroassociative memories using its recurrent circuitry. A seminal hypothesis by John Lisman postulated that during a single theta cycle, a defined set of CA3 principal neurons can activate each other to form a well defined sequence, and the spikes ( action potentials ) of these cells tend to ...
As previously mentioned, spatial memory is a cognitive function greatly intertwined with the hippocampus. While damage to the hippocampus may be a result of a brain injury or other injuries of that sort, researchers particularly investigated the effects that high emotional arousal and certain types of drugs had on the recall ability in this ...
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 ...
Exercise can also prompt the birth of new neurons in the hippocampus, which is an area of the brain that’s essential for memory and learning, Dr. Vernon Williams, sports neurologist and founding ...
Howard B. Eichenbaum (October 16, 1947 – July 21, 2017) was an American psychologist and neuroscientist who studied the hippocampus. [1] [2] He was a university professor and director of the Center for Memory and Brain at Boston University, having previously worked at Wellesley College. He was the editor-in-chief of the scientific journal ...
History and function [ edit ] During the nineteenth and early twentieth centuries, based largely on the observation that, between species, the size of the olfactory bulb varies with the size of the parahippocampal gyrus, the hippocampal formation was thought to be part of the olfactory system.
