摘要
Using the conditioned taste aversion preparation, we described the dose-effect curve for the reputed dopamine D-3 agonist (+/-)7-OH-DPAT (0, 0.001, 0.01, 0.1, 1.0, or 10 mg/kg). Rats received a 0.1% saccharin taste paired on repeated occasions with one of the 7-OH-DPAT doses. The 0.1, 1.0, and 10.0 mg/kg doses of 7-OH-DPAT produced a significant conditioned saccharin aversion. This aversion was evident regardless of whether saccharin intake of 7-OH-DPAT-treated rats was compared to their own water consumption or to saccharin intake by saline-treated rats.
