At the same time, it is not required for semantic memories. The hippocampus is known to be associated with the consolidation of episodic memories, which are memories of personally experienced events and their associated emotions. Hippocampus and our Memory episodic and semantic memory A striking feature of the memory problems that fol­ low hippocampal damage is an inability to remember recent events. Semantic memory is a form of long-term memory that comprises a person’s knowledge about the world. Hippocampus-dependent declarative memory benefits particularly from slow-wave sleep (SWS), whereas ... Memory encompasses the stages of acquisition, conso- ... (semantic) and events (episodic), and is neuroanatomically defined by its crucial dependence on Searching for the Neuroanatomy of Semantic Memory. Henry Gustav Molaison (February 26, 1926 – December 2, 2008), known widely as H.M., was an American man who had a bilateral medial temporal lobectomy to surgically resect the anterior two thirds of his hippocampi, parahippocampal cortices, entorhinal … Declarative memories are the ones associated with facts or events (semantic memory is considered one type of declarative memory; episodic is another type). The semantic memory is a derivative of episodic memory to capture facts and figures. 2.1. The use of lexical and semantic knowledge during discourse was also examined. There is a transition from episodic to semantic terms. Nevertheless, patients with hippocampal damage typically have a normal vocabulary, and their general knowledge of facts remains intact. remote semantic memory is impoverished in patients with hippocampal amnesia and that the hippocampus supports the maintenance and updating of semantic memory beyond its initial acquisition. With the perspective of time and this critical review, we arrive at the interpretation that the hippocampus does indeed make necessary contributions to semantic memory. A. change the word "episodic" to the word "implicit" B. change the word "long-term" to the word "declarative" The episodic memories are more related to hippocampus regions while the latter is known to activate frontal and temporal cortexes. to be underpinned by the hippocampus. Interestingly, In contrast to semantic memories of abstract facts and their associations, episodic memories can be represented as stories. When it comes to other functions of the hippocampus, we can say that its orbitofrontal cortex is related to the regulation of stress and emotions. Moreover, the posterior parietal cortices are responsible for spatial processing, as well as cognitive processes. Researchers demonstrated that the hippocampus functions in memory processing by creating lesions in the hippocampi of rats, which resulted in _____. The second goal of this review is to provide a synthesis of new findings on the role of the hippocampus and semantic memory. Studies of patients with amnesia reported the following neuroanatomical structures related to memory: anterior and medial part of the temporal lobe, prefrontal region, portions of the limbic system including the hippocampal gyrus and uncus, thalamic nuclei, and mammillary bodies [].Squire et al.
