Dose-dependent expression of a labile short-term CTA. Intraoral intake of 5% sucrose after contingent pairing of an intraoral infusion of 5% sucrose (6.6 ml over 6 min) with different doses of LiCl [0 (○), 19 (□), 38 (▴), or 76 (●) mg/kg] or 0.15 m NaCl (12 ml/kg). Individual rats were tested only once at one time point (n = 4–9). Intakes from Fig. 1 for the time points at 15 min, 1 hr, 6 hr, and 48 hr after 76 mg/kg were included in the analysis and data shown here. After all doses of LiCl, rats significantly decreased intraoral intake of sucrose at 15 min to 3 hr doses compared to NaCl treatment. After 6 hr, however, intraoral intake of sucrose was only significantly decreased after pairing with the highest dose of LiCl. (*) P < 0.005 vs. intake after 76 mg/kg; †P < 0.05 vs. intake after 38 mg/kg.
