Hippocampus. 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.
Memory consolidation is a category of processes that stabilize a memory trace after its initial acquisition. [1] A memory trace is a change in the nervous system caused by memorizing something. Consolidation is distinguished into two specific processes. The first, synaptic consolidation, which is thought to correspond to late-phase long-term ...
Theories Two-stage theory. The two-stage theory states that the process of recall begins with a search and retrieval process, and then a decision or recognition process where the correct information is chosen from what has been retrieved. In this theory, recognition only involves the latter of these two stages, or processes, and this is thought ...
Engram (neuropsychology) An engram is a unit of cognitive information imprinted in a physical substance, theorized to be the means by which memories are stored [1] as biophysical or biochemical [2] changes in the brain or other biological tissue, in response to external stimuli. Demonstrating the existence of, and the exact mechanism and ...
Long-term memory ( LTM) is the stage of the Atkinson–Shiffrin memory model in which informative knowledge is held indefinitely. It is defined in contrast to sensory memory, the initial stage, and short-term or working memory, the second stage, which persists for about 18 to 30 seconds. LTM is grouped into two categories known as explicit ...
Memory is a complex system that relies on interactions between many distinct parts of the brain. In order to fully understand memory, researchers must cumulate evidence from human, animal, and developmental research in order to make broad theories about how memory works. Intraspecies comparisons are key.
Learning and memory are usually attributed to changes in neuronal synapses, thought to be mediated by long-term potentiation and long-term depression. In general, the more emotionally charged an event or experience is, the better it is remembered; this phenomenon is known as the memory enhancement effect. Patients with amygdala damage, however ...
Long-term memory is the site for which information such as facts, physical skills and abilities, procedures and semantic material are stored. Long-term memory is important for the retention of learned information, allowing for a genuine understanding and meaning of ideas and concepts. [6] In comparison to short-term memory, the storage capacity ...
