Task and experimental design. (A) A trial in the reward size task - at the beginning of each trial, a visual cue signaled the amount of reward (1, 2, 4 or 8 drops) that would be delivered after a correct red-green color discrimination. After each correct trial, a new cue-reward size pair was picked from the set of 4 at random. (B) Relationship between cues and reward sizes. (C) Experimental design and timeline: unilateral Rh lesion (black) paired with contralateral injection of hM4Di vector in OFC (cyan) to produce functional disconnection when hM4Di receptors are activated with CNO.
