Stimulating Brain Waves During Deep Sleep

This study aims to better delineate profiles of insomnia subtypes in people with and without depression or PTSD across simultaneous EEG, heart rate, and body temperature monitoring over multiple days in the natural sleeping environment. Using ambulatory EEG headbands, we also aim to compare the influence of auditory stimulation on slow waves and related objective and subjective sleep measures, as well as mental well-being, daytime fatigue, and cognitive performance in healthy sleepers and people with symptoms of insomnia (with and without psychiatric comorbidities). This is a double-blind randomized control trial. The overall protocol includes a web-based screening interview and home-based data collection spanning over 5 weeks. A subset of participants will be invited for in-lab monitoring via 3 overnight visits.
