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 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 dentate gyrus (DG) is part of the hippocampal formation in the temporal lobe of the brain, which also includes the hippocampus and the subiculum.The dentate gyrus is part of the hippocampal trisynaptic circuit and is thought to contribute to the formation of new episodic memories, [1] [2] the spontaneous exploration of novel environments [2] and other functions.
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. [9] This is referred to as the Hippocampal Encoding/Retrieval model or HIPER model.
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.
[1] [6] [7] Glucocorticoids facilitate and impair the actions of stress in the brain memory process. [8] Cortisol is a known biomarker for stress. [ 9 ] Under normal circumstances, the hippocampus regulates the production of cortisol through negative feedback because it has many receptors that are sensitive to these stress hormones.
The parahippocampal gyrus (or hippocampal gyrus [1]) is a grey matter cortical region of the brain that surrounds the hippocampus and is part of the limbic system. The region plays an important role in memory encoding and retrieval. It has been involved in some cases of hippocampal sclerosis. [2] Asymmetry has been observed in schizophrenia. [3]
The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse') is a major component of the brain of humans and other vertebrates.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.
