Systemic baclofen administration attenuates responding for alcohol and sucrose reinforcement in a dose-dependent manner. If the reinforcing efficacy and response requirement for sucrose and alcohol are matched, then baclofen has similar effects on responding and patterns of drinking microstructure. We conclude that the neural mechanisms that support both ethanol and sucrose self-administration behavior are sensitive to gamma-aminobutyric acid type B modulation.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
