Extended Data Fig. 10: Decoding reward timing in the cued delayed reward task using parameters inferred in the VR task and details of recordings.
a, Discount matrix computed using the parameters inferred in the VR tasks for neurons recorded across both tasks and used in the cross-task decoding. b, Dopamine neurons cue responses in the cued delay task. Neurons are aligned as in a according to increasing discount factor inferred in the VR task. c, Top row: Decoded reward timing using discount factors inferred in the VR task. Bottom row: The ability to decode reward timing is lost when shuffling the identities of the cue responses. d, Except for the shortest delay, decoded reward timing is more accurate than shuffle as measured by the 1-Wassertsein distance (Pt = 0.6s = 1, Pt = 1.5s < 1.1 × 10−20, Pt = 3.75s < 3.8 × 10−20, Pt = 9.375s < 2.9 × 10−5). e, Breakdown of the number of recorded neurons per animal and task. The numbers in parenthesis indicate the number of neurons included in the analysis. ± indicates standard deviation across sessions. The maximum number of neurons recorded in a single session was 4 in both the cued delay task and the VR task.
