(A) Across sessions, mean (±S.E.M.) discrimination scores during the first light CS presentation (e.g., prior to the first sucrose delivery) during alcohol (1 g/kg, IG) sessions increased. By session 6, discrimination scores on alcohol sessions were significantly higher than water sessions. (B) Similar to the first discrimination score, the average discrimination score for the entire session increased during alcohol sessions, and was significantly greater than water sessions by session 6. (C) Mean (±S.E.M.) head entry rate (head entries/min) during alcohol sessions was significantly greater than water sessions throughout training. * denotes significantly different from alcohol (p<0.05).
