Figure 8: Digital reward map updating.
During the second to eighth trial, once unknown units in the maze were visited by the rat, the digital reward map would be updated after the ratbot finished the trial. In (b-I), for the ith trial, the rat explored the unknown units’ trajectory denoted as the black line. The computer then updated the reward map to (b-II) before the (i + 1)th trial. The updated area of the reward map was emphasized by the black box in the bottom row. Same situations were described in (c–e). The legend at the far right of the bottom row shows the mapping between colour and reward level (the number represent the reward level).
