From: Emotional valence sensing using a wearable facial EMG device

Grand-mean (with SE) second-by-second continuous subjective valence ratings (A) and facial electromyography data recorded from the corrugator supercilii (CS) (B) and zygomatic major (ZM) (C) muscles using the wearable device in Experiment 2. The facial EMG data were standardized within individuals.
