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 ...
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.
In later years, O'Keefe and Nadel attributed Tolman's research to the hippocampus, stating that it was the key to the rat's mental representation of its surroundings. This observation furthered research in this area and consequently much of hippocampus activity is explained through cognitive map making. [12]
The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse'), also hippocampus proper, is a major component of the brain of humans and many other vertebrates. In the human brain the hippocampus, the dentate gyrus, and the subiculum are the components of the hippocampal formation located in the limbic system.
Hence, while proper hippocampal functioning is necessary for the retention and retrieval of episodic memories, it is less necessary during the encoding and use of semantic memories. As memories age there are long-term interactions between the hippocampus and neo-cortex and this leads to the establishment of aspects of memory within structures ...
A Rotating View of the Hippocampus. The hippocampus plays an important role for remembering specific personal experiences in humans, as well as memory for sequence of events. [14] A series of lesion studies assessed the role of the hippocampus on retrospective memory. In the first delayed response task, nonhuman primates were shown two food wells.
For example, the hippocampus is believed to be involved in spatial learning and declarative learning, while the amygdala is thought to be involved in emotional memory. [ 77 ] Damage to certain areas in patients and animal models and subsequent memory deficits is a primary source of information.
For example, the hippocampus is believed to be involved in spatial and declarative memory, as well as consolidating short-term into long-term memory. Studies have shown that declarative memories move between the limbic system , deep within the brain, and the outer, cortical regions.
