Figure 4: Sucrose + quinine self-administration in an operant-response task.

Figure 4:

(A) Mice responded for 1% sucrose for 2 h/day on an FR1 schedule of reinforcement. Escalating concentrations of quinine were added to the sucrose solution after 15 sessions. (B) Active (=green) and inactive (=white) responses for sucrose. *p < 0.05, **p < 0.01 vs. inactive responses on that session (Holm-Sidak test). (C) Sucrose rewards consumed. (D) Active responses during quinine sessions.**p < 0.01 vs. 0-μM (Dunnett’s test).
