WebThe most prominent and well-known feature of the hippocampal formations is perhaps the trisynaptic pathway: first, granule cells in the DG receive synaptic inputs from the entorhinal cortex (EC) through the perforant path; second, CA3 pyramidal neurons are innervated by the mossy fibers from the DG granule cells; third, CA3 pyramidal neurons ... WebJun 12, 2007 · The trisynaptic pathway consists of a complex relay of extrinsic and intrinsic inputs operating at various steps along the way toward CA1. This pathway includes mossy fiber projections from the granule cell layer that terminate on the dendrites of pyramidal neurons within the stratum radiatum (SR) of sectors CA3/2. These latter neurons, in turn ...

"Webconnected via two main pathways: the trisynaptic pathway (TSP) and the monosynaptic pathway (MSP). The TSP runs from EC to DG, CA3, and then CA1. The projections within the TSP are sparse, enabling the formation of orthogonalized representations even with highly similar input patterns (i.e., pattern separation). " - Trisynaptic pathway
