NCT04783571

Brief Summary

The investigators will test the hypothesis that auditory stimulation (playing quiet sounds during sleep) can normalize brain activity during sleep and improve memory in patients with schizophrenia. The investigators will do this by measuring sleep and memory performance under two conditions separated by one week: receiving auditory stimulation during sleep and not receiving auditory stimulation during sleep. The investigators will study healthy subjects and outpatients with schizophrenia.

Outcome Measures

Primary Outcomes (1)

  • Differences in slow-oscillation spindle coupling

    Differences in slow oscillation-spindle coupling during non-rapid eye movement (NREM) sleep as measured by EEG between placebo and auditory stimulation naps

    Placebo and auditory stimulation naps will be approximately one week apart

Secondary Outcomes (3)

  • Differences in sleep-dependent consolidation of motor procedural memory

    Placebo and auditory stimulation naps will be approximately one week apart

  • Differences in slow oscillations

    Placebo and auditory stimulation naps will be approximately one week apart

  • Differences in sleep spindles

    Placebo and auditory stimulation naps will be approximately one week apart

Other: PlaceboOther: Auditory Stimulation

Interventions
