WebThe hippocampus is essential for the formation of conscious memories (1, 2).Although its exact role in learning and memory processes is not yet established (), several theories suggest that memory traces are initially stored in the hippocampus and subsequently transferred to neocortical areas (3–5).Within the hippocampus, the CA3 region is … WebApr 20, 2024 · Synaptic plasticity at Mossy fiber (MF)—Cornu Ammonis (CA) 3 synapses shows unique features in short-term effects and expression pattern 24.In the current …
WebNov 28, 2024 · Physiologically, the major input to the hippocampus enters via the entorhinal cortex to reach the granule cells of the DG via the perforant axonal path. Axons from the granule cells project then to the CA3 area, one of the CA field’s subdivisions, via the mossy fiber pathway. WebOne form is found at the synapse between the mossy fibers of the granule cells and the pyramidal neurons of the CA3 region. Attempts to examine the mechanism underlying this form of LTP have yielded contradictory conclusions. The authors show how the complex circuitry of the dentate gyrus and adjacent hippocampus may have caused the …
In the hippocampus, the mossy fiber pathway consists of unmyelinated axons projecting from granule cells in the dentate gyrus that terminate on modulatory hilar mossy cells and in Cornu Ammonis area 3 (CA3), a region involved in encoding short-term memory. These axons were first described … See more Mossy fibers in the hippocampus project from the dentate gyrus to CA3.
