About

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.
