Adult-born granule cells (GCs), a minor population of cells in the hippocampal dentate gyrus, are highly active during the first few weeks following functional integration into the neuronal network (young GCs), distinguishing them from less active older adult-born GCs and the major population of dentate GCs generated developmentally (together, old GCs). We created a transgenic mouse in which output of old GCs was specifically inhibited while leaving a substantial portion of young GCs intact. These mice exhibited enhanced or normal pattern separation between similar contexts that was reduced following removal of young GCs by X-ray irradiation. Furthermore, mutant mice exhibited deficits in rapid pattern completion. Therefore, pattern separation of similar contexts requires adult-born young GCs while old GCs are unnecessary, whereas older GCs contribute to the rapid recall by pattern completion. Our data suggest that as adult-born GCs age, their function switches from pattern separation to rapid pattern completion.
