WebThe trisynaptic circuit is a neural circuit in the hippocampus, which is made up of three major cell groups: granule cells in the dentate gyrus, pyramidal neurons in CA3, and pyramidal neurons in CA1. The hippocampal relay involves 3 main regions within the hippocampus which are classified according to their cell type and projection fibers. WebMar 21, 2024 · Indeed, the formation of hippocampal memory depends on a canonical trisynaptic loop formed by the strong connection among its CA1, CA3, and dentate gyrus (DG) subfields, ... In contrast to the canonical trisynaptic excitatory circuit, from DG to CA3 to CA1 pyramidal cells, interneurons perform a distinct role in the hippocampal circuit. ...
