Electrical neuroimaging results for Heartbeat-Evoked Potentials (HEP) during sound omission. (a) Group-average EEG waveforms (N = 16) showing HEPs for the comparison of Synchronous (in red) versus Baseline trials (in black; left column), for Synchronous (in red) versus Asynchronous trials (in black; center column), and for Asynchronous (in red) versus Baseline (in black; right column). (b) Group-average Global Field Power waveforms (GFP) (c) GFP statistical differences (p < 0.05 corrected for minimum duration criterion), (d) GMD statistical differences (p < 0.05 corrected for minimum duration criterion), (e) cluster permutation results showing the count of electrodes in the significant positive cluster (p < 0.05) and (f) exemplar topography differences (Synch - Baseline and Synch - Asynch) for the peaks of significant electrode count with significant electrodes highlighted in red.
