Abstract The acute effects of cigarette smoking on the human electroencephalogram (EEG) were investigated by the topographic mapping technique. Twenty-six subjects participated in this study, which involved sham smoking and real smoking of preferred cigarettes. Effects of smoking were analyzed by statistical and multivariate analysis. Analysis of variance andt-test results showed a significant decrease in the theta and alpha1 bands but a significant increase in the alpha2, beta1, and beta2 bands. Factor analysis and cluster analysis showed that there were two or three independent regions on the scalp that indicate the effects of smoking on topographic EEG. A hypothesis was formed that smoking has different effects on human EEG profiles for different brain regions and that there are individual variations in the EEG responses to smoking.
