EEG alpha reactivity and self-regulation correlates of smoking and smoking deprivation

Twelve nonsmokers, ten ex-smokers, ten deprived smokers (2-3 hours), and ten nondeprived smokers were exposed to a short-term (18-sec) vigilance task and underwent 6 min of biofeedback-assisted alpha amplitude enhancement and suppression training. Cigarette smoking was found to be associated with decreased alpha suppression to the vigilance task. However, no consistent role of cigarette smoking in alpha self-regulation emerged from the results.
