Anticipatory wheel-running in behaviorally anosmic rats.
Rats rendered behaviorally anosmic by the intranasal infusion of zinc sulfate were placed on a single daily meal, 2 hr in duration. Anosmic rats and controls showed a similar degree of wheel-running anticipatory to the meal. It was concluded that the stimulus for entrainment of meal-associated rhythmicity is not olfaction and that other characteristics of food intake need to be systematically investigated.
