![]() ![]() ![]() Boosting encoding following sleep is well motivated. ![]() ![]() Prior experiments using this method have targeted memory consolidation during overnight sleep or a nap. The first issue we explored was whether acoustic stimulation during sleep can also benefit encoding during subsequent wakefulness. However, there remain gaps in our understanding of the physiology underlying how acoustic stimulation influences memory. Efforts to enhance sleep slow waves pharmacologically, through direct or alternating current stimulation, or acoustic stimulation, suggest that the last of these approaches is the most promising for boosting declarative memory. Two key neurophysiological features of sleep-0.5 to 4 Hz slow wave activity (SWA) including the <1 Hz slow oscillations (SO), and sleep spindles, are important contributors to memory consolidation, and their enhancement has been shown to boost declarative and motor memories in humans. Manipulations performed during sleep to augment memory performance provide novel avenues for cognitive enhancement as well as understanding how sleep contributes to memory. ![]()
