Tiny groups of newborn neurons help store memories during REM sleep

A new study published in Nature Communications has found that a small number of newborn neurons in the brain help convert recent experiences into lasting memories during sleep. Researchers at the University of Tsukuba in Japan found that just a few of these adult-born neurons, when reactivated during rapid eye movement (REM) sleep, appear to play a necessary role in memory consolidation. The study also suggests that the precise timing of their a…
