    Notes: In order to examine the relationship between stimulus intensity control and tobacco smoking motivation, the cortical averaged evoked response (AER) to a number of flash intensities was studied in 10 non-smokers (NS), 10 tobacco deprived smokers (DS), and 10 non-deprived smokers (NDS). AERs to four flash intensities were recorded from the vertex (Cz) of subjects and in addition to latency and amplitude measures, the slope of the regression of amplitude with log flash intensity was obtained. Statistical analysis (employing a .05 rejection region) revealed that DS evidenced faster latencies and larger amplitudes than both NS and NDS groups who exhibited comparable responsiveness. No significant results were obtained with the slope measure. The data indicates that tobacco smoking has a “normalizing” effect on central nervous system (CNS) hyper-sensitivity observed in DS and this notion is discussed in relation to comparable physiological and behavioral work on humans and animals.

    EEG Alpha Correlates of Non-Smokers, Smokers, Smoking, and Smoking Deprivation (1977)

    Notes: Computer analysis of tonic EEG alpha amplitude and dominant alpha frequency was employed to test the hypotheses that relative to non-smokers, smokers deprived of cigarettes are in a state of cortical hypo-excitation, and that smoking induces a state of excitation comparable to that of non-smokers. Ten non-smokers, 17 deprived smokers and 13 non-deprived smokers were used to record alpha activity with a right occipital-right ear placement before and after smoking two cigarettes. Analysis of pre-smoking activity (employing a .05 rejection region) revealed a slower dominant alpha frequency in deprived smokers relative to non-smokers and non-deprived smokers. Smoking increased dominant alpha frequency in deprived smokers to a level comparable to non-smokers and non-deprived smokers. No significant results were obtained with alpha amplitude. The significance of increased alpha frequency is discussed both in relation to present results and comparable work on humans and animals, and a suggestion is forwarded regarding smoking-induced specific excitation (attention) and the maintenance of smoking behavior.

    Separate and combined effects of alcohol and tobacco on the amplitude of the contingent negative variation (1980)
    Springer

    Notes: Abstract To examine the separate and combined effects of alcohol and tobacco smoking on cortical functioning, the amplitude of the contingent negative variation (CNV) was studied during a simple reaction time task in non-smokers, tobacco-deprived smokers and nondeprived smokers in sessions involving administration of four cigarettes and/or 0.65 g/kg ethyl alcohol. Computer analysis indicated that alcohol and combined alcohol + tobacco significantly reduced the CNV amplitude in non-deprived smokers. Two sub-groups of non-smokers were identified, one showing large pre-drug CNV amplitudes and significant alcohol-induced reductions and the other showing small pre-drug amplitudes and no change in CNV amplitude after alcohol. No significant results were observed with alcohol, tobacco or alcohol + tobacco combined in tobacco-deprived smokers. The results are discussed in relation to previously reported studies which have indicated both synergistic and antagonistic interactions between alcohol and tobacco, and suggestions are forwarded regarding the experimental and clinical significance of tobacco-induced enhancement of CNV amplitude reduction by alcohol.
