Brain activity and affect: Overall and asymmetric activity of the brain lobes in affective states

BACKGROUND Studies have emphasized on the frontal EEG asymmetry as a mediator of emotional states. This research was aimed to examine the overall and asymmetric activities of the brain lobes under the affective states. METHODS A coupling EEG was recorded in an eye closed awakened condition from 40 right handed female students under the baseline and affective states. RESULTS Bilaterally decreased activities in anterior and posterior regions and also a superimposed right asymmetry in posterior regions were revealed. CONCLUSIONS Variability of frontal, temporal and parietal lobes together with a superimposed relative right posterior activity may mediate affective states.
