Comparison of PSD values for each condition (Low pleasure vs High pleasure vs Chills) for each electrode of the Epoc + headset [A] and [C] and matching ROI for EGI [B] and [D] in the theta and alpha frequency bands. (Error bars represent the standard error, * < 0.0063). Comparison of PSD values for each condition for Arousal calculation [E] (Arousal 1; prefrontal and frontal electrode (Epoc +) and Arousal 2; prefrontal and frontal ROIs (EGI). Error bars represent the standard error,* < 0.025, **<0.005.).
