Taste Reactivity to Alcohol in Rats

Rats were infused intraorally with 4 concentrations of ethanol (3%, 6%, 9%, and 12%,), and their subsequent oral, facial, and bodily responses were videotaped and analyzed. Naive rats did not display significant changes in ingestive-type responding over the concentrations tested. A significant incre...

Description
Summary:Rats were infused intraorally with 4 concentrations of ethanol (3%, 6%, 9%, and 12%,), and their subsequent oral, facial, and bodily responses were videotaped and analyzed. Naive rats did not display significant changes in ingestive-type responding over the concentrations tested. A significant increase in aversive responses was noted, with the largest number of aversive responses found with the 12% solution. Initial reactivity failed to predict subsequent consumption when rats were given free access to the same alcohol concentrations during 2-bottle tests. Reactivity testing after the period of alcohol access indicated that only the aversive responding changed significantly from the initial reactivity, with rats showing fewer aversive responses. The results indicated how the taste of alcohol is perceived by naive rats and how this perception is changed after consummatory experience with alcohol.
