Behavioral responses and CS-evoked phasic dopamine signaling during extinction training. (a) The response bias score decreased equally in both groups. (b) The food cup-directed CR declined in control animals, whereas it remained unchanged for alcohol-exposed animals. (c) Conditioned responses towards the reward-predictive lever decreased across trials in both the groups. (d) CS-evoked phasic dopamine decreased across extinction equally in both groups. *Indicates significant difference between groups with post-hoc t-tests with a Bonferroni correction (p<0.05).
