Extended Data Fig. 3: Reward randomization schemes used to determine trial types.

From: Rare rewards amplify dopamine responses

Extended Data Fig. 3

Top, ‘CS matched” randomization with equal frequencies of Normal and Uniform trials. Bottom, “PE matched” randomization with equal frequencies of 0.2 ml and 0.6 ml reward trials in each distribution. In both graphs, the y axis represents the probability of drawing the trial type (trial types drawn with replacement). The 6 trial types divided according to distribution type (N and U) and reward size (0.2, 0.4 and 0.6 ml). The number of instances in each trial type “stack” indicates the probability of drawing the trial type.
