It is unclear whether this activity represents the value associated with the expected reward or the level of motivation induced by reward anticipation. To distinguish between the two, we trained rats on a task in which we varied value independently from motivation by manipulating the size of the reward expected on correct trials and the threat of punishment expected upon errors.

Two odors indicated the size (large or small) of the reward to be delivered at the end of the trial. If an error was committed on large and small reward trials, no reward was delivered. A third odor indicated that a small reward would be delivered on correct trials and that quinine would be delivered when rats responded to the wrong well. Odor presentation lasted 500 ms and was followed by a 250–500 ms post-odor variable delay, which ended with the onset of directional cue lights. Directional lights illuminated for 200 ms on either the left or right, instructing the rat to respond to the left or right fluid well, respectively. Clear drop = sucrose; gray drop = quinine. Arrow represents direction of the behavioral response. C. Average lick rate over time during recording sessions.
