Fig. 4. The grand average time-frequency maps for ITC at six source clusters.
Six source clusters in which dipole density of gamma-band ASSR (ITC > 0.25) is significantly reduced in schizophrenia patients compared to healthy comparison subjects (Table 1). Asterisks indicate statistically significance at p < 0.05 (FDR correction applied, one tail) in comparisons of ITC between healthy comparison subjects and schizophrenia patients [(ITC in healthy comparison subjects) – (ITC in schizophrenia patients)] at each source cluster. A time window of 0–500 ms and a frequency window of 35–45 Hz were set as time-frequency window of interest, and average value within the window was calculated. ITC inter-trial phase coherence, FDR false discovery rate.
