Measures of extraversion and neuroticism were collected and resting EEG was recorded from 40 right handed undergraduate female students (19-23) on one occasion for five 30-s periods in baseline condition and in affective states. Mean log-transformed absolute alpha power was extracted from 15 electrode sites and analyzed .Results supported the role of right frontal region in negative active affect (anxiety) among introverts and emotionally stables. Asymmetry in posterior region was also suggested a role for right central region in active affect in all groups and a role for left central and parietal regions in negative passive affect (sadness) among neurotics.
