Study objectives: Hypersynchronous delta activity (HSD) is usually described as several continuous high-voltage delta waves (> or = 150 microV) in the sleep electroencephalogram of somnambulistic patients. However, studies have yielded varied and contradictory results. The goal of the present study was to evaluate HSD over different electroencephalographic derivations during the non-rapid eye A further-analysis of EEG data obtained from sleepwalkers at baseline and after sleep deprivation concluded that HSD shows a clear fronto-central gradient across all subjects, that is made more evident following sleep deprivation, and is not too surprising considering prior publications on delta wave generation.
