Long-Range GABAergic Inputs Regulate Neural Stem Cell Quiescence and Control Adult Hippocampal Neurogenesis

Bao et al. demonstrate that long-range GABAergic projections from the medial septum control adult hippocampal neurogenesis through depolarizing GABA signaling onto local PV interneurons. Functionally, these long-range inputs are required for maintaining NSC quiescence and ablating them depletes the NSC pool and impairs neurogenesis.
