<ul><li><strong>BACKGROUND</strong>: Studies have emphasized on the frontal EEG  symmetry 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.</li><li><strong>METHODS</strong>: A coupling EEG was recorded in an eye closed awakened condition from 40 right handed female students under the baseline and affective states.</li><li><strong>RESULTS</strong>: Bilaterally decreased activities in anterior and posterior regions and also a superimposed right asymmetry in posterior regions were revealed.</li><li><strong>CONCLUSIONS</strong>: Variability of frontal, temporal and parietal lobes together with a superimposed relative right posterior activity may mediate affective states.</li><li><strong>KEYWORDS</strong>: Brain Activity, Brain Lobes, Asymmetry, Affect.</li></ul>
