The left panel illustrates the EMG signal from the zygomaticus major (ZM) muscle and right panel for the corrugator supercilii (CS) muscle. Blue bars indicate muscle activity averages for liked videos, red bars for disliked videos. An asterisk (*) indicates a difference significant at p < 0.05. Error bars indicate +/- 1 standard error of the mean (SEM).
