Neurons of a distinct type in CA1 area stratum radiatum of the rat hippocampus have been found to express a direct cellular form of long-term potentiation (LTP, … There are four hippocampal subfields, regions in the hippocampus proper which form a neural circuit called the trisynaptic circuit. CA1 is the first region in the hippocampal circuit, from which a major output pathway goes to layer V of the entorhinal cortex. Another significant output is to the subiculum. CA2 is a small region located between CA1 and CA3. It receives some input from layer II of the e…
