Extended Data Fig. 13

a, Example cells showing aVEVS from Fig. 1, with reward times overlaid (black dots), showing random reward dispensing at all stimulus angles. b, The average rate of rewards was uncorrelated with visual stimulus angle (circular test for uniformity p = 0.99). c, Rat’s consumption of rewards, estimated by the reward tube lick rate, was measured by an infrared detector attached to the reward tube26. As expected, lick rate increased after reward delivery by ~4 fold and remained high for about five seconds (green shaded area). This duration is termed the “reward zone”. d, Lick rate inside the reward zone (green) was significantly larger than that outside (red, KS-test p =  2.3 x 10−54). Inside as well as outside reward-zone lick rates were uncorrelated with visual stimulus angle (circular test for uniformity p = 0.99 for both).
