Particularly, damage to hippocampal CA1 cells adversely affects memory formation, [3] and this disruption has been linked to dose-dependent levels of alcohol consumption. [4] At higher doses, alcohol significantly inhibits neuronal activity in both the CA1 and CA3 pyramidal cell layers of the hippocampus .
The hippocampus is located in the medial temporal lobe (subcortical), and is an infolding of the medial temporal cortex. [1] The hippocampus plays an important role in the transfer of information from short-term memory to long-term memory during encoding and retrieval stages. These stages do not need to occur successively, but are, as studies ...
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.
This supports the idea that damage to any part of the extended hippocampal memory system causes similar memory deficits. [4] Other aspects of cognition, such as social cognition and language ability, remain intact after fornix damage. Lesion findings have been extended by work using the non-invasive in vivo technique diffusion-weighted imaging.
The hippocampus deals largely with memory consolidation, [35] where information from the working memory and short-term memory is encoded into long-term storage for future retrieval. Amnesic patients with damage to the hippocampus are able to demonstrate some degree of unimpaired semantic memory , despite a loss of episodic memory , due to ...
These memory decisions are made based on matching already-existing memories, before the onset of pathology, to the current situation. According to Gilboa et al., patients with localized hippocampal damage can score well on a test if it is based on familiarity. [22]
Parietal lobe also assists with verbal short term memory and damage to the supramarginal gyrus cause short term memory loss. [20] Damage to the parietal lobe results in the syndrome ‘neglect' which is when patients treat part of their body or objects in their visual field as though it never existed. Damage to the left side of the parietal ...
The hippocampus is responsible for the formation of long term recognition memories. In other words, this is the part of the brain that allows us to associate a face with a name. Because of its close relationship with memory formation, damage to the hippocampus is closely related to Alzheimer's disease.
