WebDec 24, 2024 · The PV-containing interneurons of the hippocampal formation are located mainly in the pyramidal and granule cell layers and the hilum . They are mostly GABAergic basket cells and axo-axonic cells exerting inhibition on cell bodies, proximal dendrites, and axon initial segments [ 43 ]. WebThe hippocampus mediates several higher brain functions, such as learning, memory, and spatial coding. The input region of the hippocampus, the dentate gyrus, plays a critical role in these processes.
