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 a structure in the brain that has been associated with various memory functions. It is part of the limbic system, and lies next to the medial temporal lobe. It is made up of two structures, the Ammon's Horn, and the Dentate gyrus, each containing different types of cells. [1]
There is now almost universal agreement that hippocampal function plays an important role in spatial coding, but the details are widely debated. [62] Later research has focused on trying to bridge the disconnect between the two main views of hippocampal function as being split between memory and spatial cognition.
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.
A key physiological function of the CA3 is encoding heteroassociative memories using its recurrent circuitry. A seminal hypothesis by John Lisman postulated that during a single theta cycle, a defined set of CA3 principal neurons can activate each other to form a well defined sequence, and the spikes ( action potentials ) of these cells tend to ...
Encoding allows a perceived item of use or interest to be converted into a construct that can be stored within the brain and recalled later from long-term memory. [1] Working memory stores information for immediate use or manipulation, which is aided through hooking onto previously archived items already present in the long-term memory of an ...
The dentate gyrus (DG) is one of the subfields of the hippocampus, in the hippocampal formation. The hippocampal formation is located in the temporal lobe of the brain, and includes the hippocampus (including CA1 to CA4) subfields, and other subfields including the dentate gyrus, subiculum, and presubiculum.

Memory is retained in the hippocampus for up to one week after initial learning, representing the hippocampus-dependent stage. [20] During this stage the hippocampus is 'teaching' the cortex more and more about the information and when the information is recalled it strengthens the cortico-cortical connection thus making the memory hippocampus ...
