The hippocampus is known to play a role in the encoding of memory that associates between a face and a name. The experiment began by dividing encoding blocks, in which the participants viewed and attempted to memorize the faces paired with the names, from retrieval blocks, in which the participants were shown only the faces and asked to match ...
The hippocampus has been shown to become active in semantic and episodic memory. [70] The effects of Alzheimer's disease are seen in the episodic part of explicit memory. This can lead to problems with communication. A study was conducted where Alzheimer's patients were asked to name a variety of objects from different periods.
Activation in the hippocampal region associated with episodic memory encoding has been shown to occur in the rostral portion of the region whereas activation associated with episodic memory retrieval occurs in the caudal portions. [20] This is referred to as the Hippocampal memory encoding and retrieval model or HIPER model.
The hippocampus is also involved in memory consolidation, the slow process by which memories are converted from short to long term memory. This is supported by studies in which lesions are applied to rat hippocampi at different times after learning. [2] The process of consolidation may take up to a couple years.
The hippocampus regulates memory function. Memory improvement is the act of enhancing one's memory. Factors motivating research on improving memory include conditions such as amnesia, age-related memory loss, people’s desire to enhance their memory, and the search to determine factors that impact memory and cognition.
Neuroscience acknowledges the existence of many types of memory and their physical location within the brain is likely to be dependent on the respective system mediating the encoding of this memory. [9] Such brain parts as the cerebellum, striatum, cerebral cortex, hippocampus, and amygdala are thought
This encoding process is an important aspect of recognition memory because it determines not only whether or not a previously introduced item is recognized, but how that item is retrieved through memory. Depending on the strength of the memory, the item may either be 'remembered' (i.e. a recollection judgment) or simply 'known' (i.e. a ...
The hippocampus is considered the memory center for the brain and is responsible for storing, encoding, retrieving, and reconsolidating memories. [8] Studies indicate that people who have PTSD may have a "shrunken" hippocampus, some estimates indicate that there may be up to a decrease in a range of 5-26%. [ 10 ]
