Chapter 380presentation of both angry and sad facial expressions did not differ significantly from neutral expressions (see Fig. 6b and Table 14 in Online Resource 3). On top of that, activity over the Zygomaticus major region was not observed to be altered if any of the emotional bodily expressions or facial cues compared to their neutral counterparts were shown.Figure 6. Time course of the filtered, baseline-corrected and z-scored facial electromyography (EMG) signal over (a) the corrugator supercilii region and (b) the zygomaticus major region related to passive viewing of prototypical facial expressions by emotion category. The coloured shaded areas around the values indicate standard errors of the predicted means. Signals were plotted and analyzed in time bins of 100ms each. Coloured vertical lines (and grey-shaded background areas between them) highlight time bins in which the EMG signal when viewing an emotional expression is significantly different from neutral in both samples (training and test), with the colour indicating the corresponding emotion category.
