Figure 1.
Effect of systemic administration of lithium chloride (LiCl, 125 mg/kg i.p., CS+, or saline i.p., CS−) on average sucrose intake. CS+ or CS− were administered 1 h after the 20 min drinking session of the last training day (acquisition). Each histogram (n = 13 in each group) represents the average + s.e.m. of sucrose solution intake (ml) in 20 min. *p < 0.05 vs. US− (One-Way ANOVA followed by LSD post-hoc test).
