WebFeb 29, 2008 · The hippocampus is an area of the brain involved in learning and memory. It contains parallel excitatory pathways referred to as the trisynaptic pathway (which carries information as follows: entorhinal cortex → dentate gyrus → CA3 → CA1 → entorhinal cortex) and the monosynaptic pathway (entorhinal cortex → CA1 → entorhinal cortex). WebMay 27, 2014 · The classic trisynaptic circuit EC layer II → DG → CA3 → CA1 seems to be related to the acquisition of new memories, whereas the interaction between EC and CA1 neurons (monosynaptic pathway) is thought to contribute to the strength of previously established memories (Cohen and Squire, 1980).
