Optical controlling reveals time-dependent roles for adult
... As the morphological and physiological phenotypes of adult-born cells change markedly as they mature, they may have distinct roles at different stages following integration into hippocampal circuits. Adult-born dentate granule cells (DGCs) extend dendrites receive functional input from the existing ...
