The table lists the neuronal subtypes that innervate each layer of the dentate gyrus. 5-HT, 5-hydroxytryptamine; AA, axo-axonic; abGC, adult-born granule cell; ACh, acetylcholine; BC, basket cell; DA, dopamine; eGC, ectopic granule cell; GC, granule cell; HICAP, interneurons with a hilar cell body with axon targeting the commissural/associational pathway; HIPP, hilar cells that project to the terminal zone of the perforant path; LPP, lateral perforant path; Mamm, supramammillary; MC, mossy cell; mGC, mature granule cell; MOPP, interneurons with a molecular layer cell body that project to the terminal zone of the perforant path; MPP, medial perforant path; NA, noradrenaline; NG, neurogliaform; smGC, semilunar granule cell; vCA3, ventral CA3.
