"Brain rhythm predicts real-time sleep stability"

March 3, 2011



A study appearing in the March 3rd issue of PloS One found that alpha waves detected during sleep indicate heightened sensitivity to noise. In this study, lead by Scott McKinney of Massachusetts General Hospital's Division of Sleep Medicine, researchers tested arousability using a variety of sounds and volumes, and  found that sleepers were more likely to be aroused from sleep when alpha waves were highly expressed. Using this method to quantify arousal probability in real time, it may be possible to develop more precise, adaptable medications to induce sleep.
