Abstract
Smoking/nicotine has been shown to increase brain arousal states, yet previous studies have failed to distinguish between absolute improvements due to nicotine versus relief from withdrawal symptoms in smokers. This study examined the electrocortical response to nicotine in a nonsmoking population, in order to negate potential withdrawal symptoms. Twenty right-handed, nonsmoking participants were administered nicotine (6 mg) or placebo gum within a double-blind, repeated-measures design. In each session, EEG was recorded during a 2-min, resting, eyes-open condition. Nicotine administration (vs. placebo) resulted in significantly greater frontal (specifically left-frontal) alpha2 power. Similar to previous findings in smokers. The absence of slow-wave changes following nicotine in nonsmokers suggest that these previous results in smokers may be related to withdrawal state.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
