Abstract: The laterality of frontal EEG would be regarded as an index of the capability of emotion regulation. The present report reviewed literature based on the following findings: individuals with emotion disorder showed decreases in left frontal activity; individuals with high emotion regulation capability showed enhancement of left frontal activity; the EEG activity asymmetry of frontal predicated the risk of anxiety and depression; emotion regulation companied higher left frontal activity; bio-feedback training on increasing left frontal activity prompted emotion regulation. It suggested that future studies should provide findings that higher capability of emotion regulation would prompt left frontal activity, which could help to make a conclusion that the frontal EEG asymmetry serves as an index of the capability of emotion regulation.

Key words: frontal lobe, EEG laterality, emotion regulation
