Fig. 3: Sensor level sensory attenuation effects.

A Grand-average butterfly, baseline corrected (−300 and −100 ms), ERF-time series were computed for all 248 sensors in 49 HCs, 109 CHR, and 23 FEP. Overlayed on the ERFs traces are topographical distribution plots of the M100 component in axial-magnetometer representation, plotted for data averaged over the 110–140 ms latency window. The area highlighted in gray indicates the sensory attenuation effect. B Topographical distributions in planar-magnetometer representation t values for the SAP effect across and within groups. Significant clusters of sensors (p < 0.05, two-tailed) are highlighted with white dots. HC healthy controls, CHR-P clinical high-risk psychosis, FEP first-episode psychosis.
