Mu Suppression Mediates the Social Modeling of Eating Effect in Relation to Lateralized Frontal Activation and BMI

Under the guise of rating empathy, female undergraduates watched a video confederate “incidentally” consume either a small or large food intake while EEG was recorded. Greater mu rhythm suppression over sensorimotor sites predicted modeling of consumption among those with greater left frontal asymmetry and a BMI within the normal range.
