Abstract

In this study we analyzed broadband, whole-head MEG activity to investigate affective processing in the human brain and assess whether spectral power in nonoverlapping frequency bands correlates preferentially with specific anatomical locations and distinct emotions elicited by affective stimuli that differed in valence from unpleasant to pleasant and arousal from low to high. We analyzed recordings from 20 normal young adults using linear mixed effects models computed separately in each frequency band on a reduced set of recording sites represented by 8 principal components. Our results showed statistically significant differences between the pleasant and neutral conditions in all frequency bands and between the pleasant and unpleasant condition in the theta band.
