Effects of sham smoking on dominant EEG alpha frequency.

In this and the subsequent figures, the scalp electrode placements are shown on the x-axis and the mean ± SE dominant alpha frequency (in Hz) on the y-axis. A. Data obtained from experiment 1. B. Data obtained from experiment 2. In this and subsequent figures: *p <.05, **p<.01, ***p<.001 indicated the significant alpha level that is produced by the two way ANOVA with repeated measures. Note that sham smoking increases selective right hemisphere neocortical dominant alpha frequencies. Slide file numbers are listed in the lower right hand corner.
