“…16,17 Given that one of the most commonly reported reasons individuals use tobacco is to improve attention and arousal, [8][9][10][11] assessing N2, P3b, and alpha suppression before and after product usage may prove useful in objectively identifying which tobacco products elicit a preferential response. In line with this notion, previous research has shown that traditional cigarettes, or nicotine alone, can enhance alpha suppression, 18-21 N2, 22 and P3b amplitude. [22][23][24] EEG and ERPs have previously been used as a way to assess the effect of tobacco or nicotine on attention and brain state arousal.…”

“…23,24 Although the P3b was not significantly influenced by product type, this may reflect the relatively smaller sample size of the present investigation. Previous work has also generally demonstrated modulation of the N2 in response to nicotine and tobacco use, although the results have been mixed (for a review see: Pritchard et al 22 ). In the present report, N2 was larger for Skoal compared to Ariva/Verve.…”

Introduction: Adequate evaluation of novel tobacco products must include investigation of consumers' psychological response to such products. Traditionally, subjective scales of product liking have been used to assess consumer acceptability of tobacco products. However, subjective scales may miss cognitive changes that can only be captured by direct neurophysiological assessment. The present investigation explored the viability of using electroencephalography (EEG), in combination with traditional subjective measures, to assess consumer acceptability of five smokeless tobacco products. Given previous work linking product liking to arousal/attentional (executive function) enhancement, we focused on EEG measures of attention/arousal to objectively characterize cognitive changes associated with tobacco product use. Methods: During five separate laboratory visits, smokeless tobacco users used Verve discs, Ariva dissolvables, Skoal snuff, Camel snus, or Nicorette lozenges. The N2 and P3b event-related potential components elicited by an oddball task were used to index attentional changes before/after product usage. Additionally, resting state alpha band EEG activity was analyzed before/after product usage to index cortical arousal. Results: Although analyses of the subjective results provided limited inference, analyses of the electrophysiological measures, particularly the alpha suppression measure, revealed robust differences between products. Skoal elicited significantly enhanced alpha suppression compared to all four other products tested. Additionally, alpha suppression was found to correlate positively with subjective measures of satisfaction and psychological reward, but was unrelated to perceived aversion. Conclusions:The present results provide evidence that electrophysiological measures can yield important insights into consumer acceptability of novel tobacco products and are a valuable complement to subjective measures. Implications: This study is the first to employ a combination of electrophysiological measures and traditional subjective assays in order to assess the consumer acceptability of smokeless tobacco products. The results highlight the importance of adopting a multidimensional/multi-method approach to studying the consumer acceptability of tobacco products.

“…P300 Abnormalities in cocaine, methamphetamine, heroin addiction, and alcoholism. The P300 component of the ERP, occurring 300-to 600-msec poststimulus, is the most widely used ERP in psychiatry and other clinical applications (Polich & Herbst, 2000;Polich, Pollock, & Bloom, 1994;Pritchard, 1981Pritchard, , 1986Pritchard, Sokhadze, & Houlihan, 2004). The amplitude of the P300 reflects the allocation of attentional resources, whereas the latency is considered to reflect stimulus evaluation and classification time (Katayama & Polich, 1998;Polich & Herbst, 2000).…”

“…Numerous studies have explored effects of smoking and nicotine on event related potentials (ERPs) [1,2], including selected ERP components [3] and the P300 [4]. Most of these studies reported increased amplitudes and/or decreased latencies supporting the hypothesis that nicotine generally enhances brain processing.…”

Abstract:The effects of smoking and nicotine on ultralate laser evoked potentials (LEPs), the EEG responses to C-fiber stimulation by a laser beam, were investigated in humans. Ultralate LEPs were repeatedly measured in two sessions, one after smoking, and the other in abstinence from smoking. The dominant frequency of the background EEG alpha activity, heart rate and venous plasma nicotine concentration were also measured. The peak-to-peak amplitude of the two major components (N2 and P2) of ultralate LEPs was significantly correlated both with the plasma nicotine concentration and with the background alpha frequency. The results suggest an arousal effect of nicotine on C-fiber mediated pain. The effect of nicotine on C-fiber LEPs was in the opposite direction of that on A fiber LEPs. The difference between C and A fibers might indicate a difference in effects of nicotine on first and second pain responses.
