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

Abstract

• BACKGROUND: 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.
• 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.
• KEYWORDS: Brain Activity, Brain Lobes, Asymmetry, Affect.
