In-Ear EEG Auditory Neurofeedback Towards Unobtrusive Sleep Enhancement

Sleep is not only essential for maintaining quality of life, but also one of the most important factors in sustaining long-term health and fending off disease. Slow wave sleep (deep sleep) mediates the body's natural mechanisms for replenishing and repair. While pharmacological and other clinical interventions target treatment of sleep disorders, novel approaches are critically needed to improve sleep quality. This review assesses using ear-electroencephalography (ear-EEG) for monitoring and modulating slow wave sleep.
