Neural correlates of prosocial behavior in infancy: Different neurophysiological mechanisms support the emergence of helping and comforting

► We assessed infants' resting state EEG activation asymmetries. ► We examined neural correlates related to infants' prosocial behavior. ► Different neural patterns were associated with different forms of prosocial action. ► Comforting behavior was associated with frontal activation asymmetries. ► Helping behavior was solely related to temporal asymmetries.
