Assessment of ethanol and nicotine interactions using a reinforcer demand modeling with grouped and individual levels of analyses in a long-access self-administration model using male rats.

This study examines ethanol and nicotine interactions using reinforcer demand modeling in rats, finding group and individual level differences in demand and reciprocal effects during concurrent self-administration.

Varenicline rescues nicotine-induced decrease in motivation for sucrose reinforcement

This study investigates how varenicline affects nicotine-induced decreases in sucrose motivation, finding that varenicline rescues this reduction in both behavioral economics and passive consumption tests.

Inactivation of posterior but not anterior dorsomedial caudate-putamen impedes learning with self-administered nicotine stimulus

This study shows that inactivating the posterior dorsomedial caudate-putamen impairs learning of a nicotine-sucrose association in rats, while the anterior region does not.
