Integration of Auditory, and Deep Brain Stimulation to Enhance Deep Sleep in Parkinson's Disease

"In this project, the intervention is a presentation of low-volume non-arousing auditory stimuli during deep NREM sleep via attached headphones. Stimuli will be applied targeting the up-phase of slow waves to enhance sleep slow-wave activity.~Previous studies showed that this procedure does not lead to reduced sleep quality nor result in changed sleep architecture. Therefore, no negative consequences as a result of our intervention are to be expected. In fact, it is currently applied in several other studies including children, adults, and the elderly. Importantly, stimulation is not arousing, as the sounds presented during deep sleep are brief (50 ms) and at low volume (around 50 dB). In case of arousal during sleep (detected using the surface EEG signal), the volume will be adjusted."
