Effects of varenicline alone on rats trained to discriminate N+A. Mean (±S.E.M.) discrimination score (head entries during the 15-s light CS minus head entries during 15 seconds before light onset, A) and locomotor rate (beam breaks per minute, B) following varenicline injection in the feature positive group. Mean(±S.E.M.) discrimination score (C) and locomotor rate (D) following varenicline injection in the feature negative group. *-denotes significantly different from saline (p < 0.05). +-denotes significantly different from N+A baseline (p < 0.05).
