Involvement of Adult Hippocampal Neurogenesis in Learning and Forgetting

Figure 1

Anatomy of hippocampal network. The diagram illustrates the monosynaptic and the trisynaptic pathways in the hippocampus. The monosynaptic pathway consists of a direct projection from the EC to CA1 or CA3, whereas the trisynaptic pathway consists of sequential projections from EC to DG, CA3, and then to CA1. EC: entorhinal cortex; DG: dentate gyrus; CA: cornu ammonis.
