From: The effect of cardiac phase on distractor suppression and motor inhibition in a stop-signal task

Data segmentation for analysis of event-related potentials. For each trial, data segments of interest were of length − 100 to 1000 ms around an event (marked by beige finger), except for motor processing of the stop signal (marked by blue finger) for which segments of -100 to 750 ms were extracted. To note, visual distractors were displayed throughout the whole trial up to feedback screen onset; however, visual evoked potentials of movement onsets (systole condition, yellow: 290 ms following R-peak; diastole condition, dark green: at R-peak; control condition without distractors, dashed black: at R-peak) were only analysed for those preceding go signal appearance (in total, three onsets). Similarly, heartbeat evoked potentials were only analysed for the first three heartbeats. The go signal (light green arror) appeared at random between the third and fifth heartbeat (lower.
