Relations among EEG-alpha asymmetry, BIS/BAS, and dispositional optimism

- We evaluate the association of BAS, BIS, and optimism with EEG-alpha asymmetry.
- Higher BAS was related to greater left-sided frontal activation (BA11).
- Higher optimism was related to left-frontal and right-parietal activations (BA10/31).
- sLORETA served to localize cortical sources in the EEG-alpha band (8-13 Hz).
