Brain activity and affect: overall and asymmetric activity of thebrain 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 inposterior regions were revealed.conclusions: variability of frontal, temporal and parietal lobes together with a superimposed relative right posterioractivity may mediate affective states.
