The effects of cigarette smoking on the electroencephalogram (EEG) of smokers were examined in a study involving both task and no-task conditions. Non-smoking subjects were employed as controls. In light inhaling smokers, (depth of inhalation inferred from pre- to post-smoking changes in tidal breath carbon monoxide), smoking was found to attenuate EEG activity in the delta, theta, and alpha frequency bands, as well as facilitate behavioral performance. For theta, the attenuation was lateralized over the right frontal cerebral hemisphere. In deep inhaling smokers, smoking produced a symmetrical central midline increase in beta2 magnitude, an EEG effect that in the benzodiazepine literature is associated with anxiety relief.
在一项涉及任务和非任务条件的研究中，对吸烟对吸烟者脑电图（EEG）的影响进行了检查。以不吸烟的受试者作为对照。在轻度吸入吸烟者中（根据吸烟前后潮气一氧化碳变化推断吸入深度），发现吸烟会减弱δ、θ和α频段的脑电图活动，并促进行为表现。对于θ频段，衰减在右侧额脑半球呈侧向化。在深度吸入吸烟者中，吸烟使β2波幅在中央中线处对称增加，在苯二氮䓬文献中，这种脑电图效应与焦虑缓解有关。
