吸烟对中枢神经系统的影响可直接用脑电图（EEG）来评价。尼古丁戒断和随后的替代已被研究过，但对脑电活动产生了相互矛盾的影响。我们研究了20名受试者按自己的节奏吸2支香烟的影响。在闭眼清醒状态下，使用双极导联，使用EEG程序记录EEG。Delta屈光度在中心-后部头部区域降低。θ功率和α波段下半部分的功率下降。β功率和功率在上半部分的α波段显着增加额颞头部区域。对通常频带下的频谱的检查表明，吸烟对EEG功率的许多影响可能是由于整体功率谱向更高频率的移动，而不是由于特定频带的活动改变。
The effects of cigarette smoking on the central nervous system can be assessed directly using the electroencephalogram (EEG), Nicotine withdrawal and subsequent replacement have been studied, but have produced conflicting effects on brain electrical activity, We studied the effect of smoking 2 cigarettes at subjects' own pace in 20 subjects. EEG was recorded using the EEGSYS program in the eyes-closed awake state using a bipolar montage. Delta power decreased in central-posterior head regions. Theta power and power in the lower half of the alpha band decreased. Beta power and power in the upper half of the alpha band increased significantly over frontotemporal head regions. Examination of spectra underlying the usual frequency bands revealed that many effects of smoking on EEG power probably resulted from a shift of the overall power spectrum toward higher frequencies, rather than resulting from alterations in activity in specific frequency bands.
