News Finding: It sounds like a strong wind.
Paper Finding: Latency of these components did not differ between inphase and out-of-phase stimulation (p > 0.347).
News Context: Brown noise generally has fewer higher frequencies than white or pink noise, and tends to sound rougher, Breus says. It sounds like a strong wind. But there may be a good reason to choose pink.
Paper Context: Amplitude of the late negative component was slightly smaller for the out-of-phase than in-phase stimulation (p = 0.019 for comparison at Cz), which probably reflects reduced neocortical excitability when the stimulus is presented during the SO down state . Latency of these components did not differ between inphase and out-of-phase stimulation (p > 0.347). Our data indicate that an enhancement of SO activity and overnight memory consolidation by auditory stimulation depends essentially on a timing in phase with SO up states.
