Experiment 2B. IG sugar conditioning in food-restricted FVB mice trained 1 h/day. Intake of the CS+ solution was paired with IG infusions of either 16% fructose (A) or 16% glucose (B). Intake of the CS− solution was paired with IG infusions of water. The left side of each panel shows total 1-h fluid intake (oral CS intake plus IG infusate) during each of the six one-bottle training sessions. The CS− solution was offered in sessions 1, 3, and 5, and the CS+ solution was offered in sessions 2, 4, and 6. The right side of each panel shows mean total daily intake during the reinforced (Rein) two-bottle preference test, in which the CS+ was paired with IG sugar infusion, and mean daily intake during the nonreinforced (NR) two-bottle test, in which the CS+ was paired with IG water infusion. Values are expressed as means ± SE total daily intakes. Numbers atop bars represent mean percent preference for the CS+ solutions. Significant differences (*P < 0.05) between CS+ and CS− intakes during two-bottle tests are shown.
