Figure S1 - Low Dose Nicotine and Antagonism of β2 Subunit Containing Nicotinic Acetylcholine Receptors Have Similar Effects on Affective Behavior in Mice

Operant responding during individual sessions in absence of drug. Variability in Pre-CS responding was observed in mice exposed to both 0.1 and 0.3 mA footshock unconditioned stimulus (US) over within-subject delivery of both nicotine and DHβE. The timing of the conditioned stimulus (CS) may have contributed to this variability, as operant responding fluctuated within individual sessions.
