Abstract
Recently research groups have reported that the depth and/or
duration of Slow Wave Sleep (SWS) can be increased and
memory consolidation can be improved by playing short
sounds with approximately 1-2 second intervals during or
prior to SWS. These studies have used sounds with neutral
or negative valence: sinusoidal 1-kHz tones or short pink
noise bursts. We have confirmed memory improvement with
own experiments using short pink noise bursts. Since music
therapy research shows beneficial effects of pleasant, natural
sounds and music, the sounds in the experiments may have
been suboptimal, and we are currently extending these
finding using optimized sound stimulus. In this work in
progress experiment setup is described.
