Early- and late-latency gamma auditory steady-state response in schizophrenia during closed eyes: does hallucination status matter?

Highlights • Early-latency gamma auditory steady-state responses are diminished in schizophrenic subjects and do not depend on hallucination status when recorded with closed eyes. • Late-latency gamma responses do not differ between healthy and schizophrenic subjects and do not depend on hallucination status when recorded with closed eyes. • Frequency of early-latency gamma is related to negative symptoms, whereas delayed build-up of entrainment is related to hallucination prevalence.
