Phase-Amplitude Coupling between EEG and EDA While Experiencing Multimedia Content

Emotion is a dynamic process that affects social relationships and influences the mechanisms of rational thinking and decision making. The influence of emotion on reasoning has gained a lot of attention in computer science. One approach to incorporating emotions into computers is by extracting features from various physiological signals and inferring the corresponding emotions or emotional dimensions. However, physiological processes are dynamic rather than static, and physiological signals mainly interact with each other during emotional processes rather than act individually. This study suggests that dynamical interdependencies of various signals that emanate from either the peripheral nervous system or the central nervous system might be involved in the emotional experience. Specifically, EEG (electroencephalography) signals captured from the temporal lobe are coupled with a narrow-band skin conductance response (SCR) while subjects are watching music clips, indicating that signals from the auditory cortex interact with SCR during this experience.
