Figure 4

Mean (± SEM) Lick Score of need-free SA and SP rats in response to increasing concentrations of sucralose presented in random order during brief-access tests in the Davis rig. Scores above 0.0 indicate that the animals licked more to sucralose relative to water while scores below 0.0 indicate that the animals licked more to water relative to sucralose. Comparable to Figure 3, SA and SP rats treated the two lowest concentrations of sucralose as similar to water. Interestingly, in a water-replete state, SA and SP rats displayed reliable differences in their licking response at a one log unit lower concentration of sucralose (0.25 mM) compared to the fluid-deprived state (2.5 mM). *SP rats greater than SA rats, Ps < 0.05.
