Time-series cross-correlation of physiological responses during emotion induction: A frontal alpha asymmetry and heart rate study

Abstract

is possible that facial expression was induced by the synchronization of frontal alpha asymmetry and ANS activity. In addition, when they watched one of the positive clips, frontal alpha asymmetry fluctuation was preceded by HR variation. This indicated that ANS response might influ ence activity of cerebral area where frontal alpha asymmetry arises.
