Explicit memory (or declarative memory) is one of the two main types of long-term human memory, the other of which is implicit memory. Explicit memory is the conscious, intentional recollection of factual information, previous experiences, and concepts. [1] This type of memory is dependent upon three processes: acquisition, consolidation, and ...
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 ...
They are an ideal animal to use for the study of memory. The assessment of learning and memory in rodents has been employed in scientific research for a long time, and there are many experimental methods used. Generally tests of spatial memory employ maze designs where the rodent must run a maze in order to receive a food reward.
Both implicit and explicit memory are types of long-term memory, which is defined by the transfer of information from short-term memory into long-term storage in order to create enduring memories.
The hippocampus is important for explicit memory. The hippocampus is also important for memory consolidation. The hippocampus receives input from different parts of the cortex and sends its output out to different parts of the brain also. The input comes from secondary and tertiary sensory areas that have processed the information a lot already.
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 EC has dual functions in processing information for explicit memory storage: First, it is the main input to the hippocampus. [2] The EC projects to the dentate gyrus via the perforant pathway and by this means provides the critical input pathway in this area of the brain, linking the association cortices to the hippocampus.
The rhinal cortex is proposed to be part of the neural circuit for explicit memory. [1]Studies comparing the results of selective lesions of the hippocampus and of the rhinal cortex found that lesions of the hippocampus alone did not impair performance on object recognition tests, but that lesions of the rhinal cortex alone caused severe anterograde and retrograde impairments on these tests.
