Figure 4. Average daily consumption (g/kg/24h) of each concentration of quinine solution, or average preference ratio of the 0.1 mM quinine solution, by control mice or mice that had a prior history of 1, 3, or 6 cycles of DID.

Figure 4

Animals in the 6-cycle DID group displayed significantly elevated voluntary consumption (A) and preference (B) of quinine at the 0.1 mM concentration relative to both the control and 1-cycle DID groups. All values are mean ± SEM; * signifies that p < 0.05 relative to the water-drinking control group; † denotes that p < 0.05 relative to 1-cycle DID group.
