Effects of salvA on the number of ratios completed for sucrose pellets prior to 15 min of inactivity (breakpoint). a) Compared to vehicle and salvA (0.25 mg/kg), salvA (2.0 mg/kg) significantly lowered breakpoint in the PR schedule. b) There were no significant differences in FR5 breakpoints across salvA dose. In both graphs, each bar represents the mean (+sem) breakpoint during the session (n=10 rats). *p<0.05 compared to vehicle and salvA (0.25 mg/kg), Tukey's Honestly Significant Difference tests
