The CA3 “backprojection” to the dentate gyrus

HE Scharfman - Progress in brain research, 2007 - Elsevier
The hippocampus is typically described in the context of the trisynaptic circuit, a pathway that
relays information from the perforant path to the dentate gyrus, dentate to area CA3, and
CA3 to area CA1. Associated with this concept is the assumption that most hippocampal
information processing occurs along the trisynaptic circuit. However, the entorhinal cortex
may not be the only major extrinsic input to consider, and the trisynaptic circuit may not be
the only way information is processed in hippocampus. Area CA3 receives input from a …
