This study examined how olfaction impacts ingestive responses of mice to sugar solutions. Experiment 1 asked whether naïve C57BL/6 (B6) mice could identify 1M glucose, fructose or sucrose solutions based on odor cues, during a 30-min two-bottle acceptability test. We tested mice both before and after they were rendered anosmic with ZnSO4 treatment. We used two indirect measures of odor-mediated response: number of trials initiated and latency to initiate licking. Before ZnSO4 treatment, the mice learned how to identify 1M glucose and fructose (but not sucrose) solutions based on odor cues. ZnSO4 treatment eliminated their ability to identify the glucose and fructose solutions. Experiment 2 asked whether two days of exposure to a 1M glucose, fructose or sucrose solution improved identification of the same sugar solution. Following exposure, the B6 mice identified all three sugar solutions based on odor cues. Experiment 3 asked whether T1R3 knockout mice (i.e., mice lacking the T1R3 subunit of the T1R2+R3 sweet taste receptor) could learn to discriminate 0.44M glucose and fructose solutions based on odor cues. All mice were subjected to a 1-hr preference test, both before and after exposure to the 0.44M glucose and fructose solutions. During exposure, the experimental mice received ZnSO4 treatment, while the control mice received saline treatment. Before exposure, neither type of mouse preferred the glucose solution. After exposure, the control mice preferred the glucose solution, while the experimental mice did not. Our results reveal that mice can learn to use odor cues to identify and discriminate sugar solutions.
