Accumulating evidence suggests that global depletion of adult hippocampal neurogenesis influences its function and the timing of the depletion impacts the deficits. However, behavioral roles of adult-born neurons during their establishment of projections to CA3 pyramidal neurons remain largely unknown. Here we combined retroviral and optogenetic approaches to birth-date and reversibly control a group of adult-born neurons in adult mice. We show that adult-born neurons form functional synapses on CA3 pyramidal neurons as early as 2 weeks after birth, and that this projection to the CA3 area becomes stable by 4 weeks in age. Newborn neurons at this age exhibit enhanced plasticity compared to other stages. Notably, we found that reversibly silencing this cohort of ~4 week-old cells after training, but not cells of other ages, substantially disrupted retrieval of hippocampal memory. Our results identify a restricted time window for adult-born neurons exhibiting an essential role in hippocampal memory retrieval.
