A. Response rates (responses/min) of animals trained to self-administer food pellets (45mg) in 1-h/day sessions over a multiple number of 1-h food-self administration (FSA1-3) and extinction (EXT1-5) sessions. **p<0.01, ***p<0.001, Bonferroni’s multiple comparison test following significant RM one way-ANOVA, where FSA1-3 were significantly different from all EXT sessions. B. Response rates (responses/min) for each 5-min block interval for the average of the last three food self-administration sessions prior to extinction and the first extinction session. C. Response rates (responses/min) for the first 5-min interval of the food self-administration and EXT sessions. *p<0.05, **p<0.01, Bonferroni’s multiple comparison test after significant RM two- and one- way-ANOVA (for B and C, respectively), where EXT sessions are compared to FSA. All response rates are expressed as means (±SEM) with n = 31 for all figures.
