Slow oscillations in brain activity, which occur during so - called slow - wave sleep, are critical for retaining memories.
We presented the acoustic stimuli whenever a slow oscillation «up state» was upcoming, and in this way we were able to strengthen the slow oscillation, showing higher amplitude and occurring for longer periods,» explains Dr. Born.
