Supplementary Figure 4: Dopamine signals in delayed Go trials.
From: Action initiation shapes mesolimbic dopamine encoding of future rewards
Upper panels display the unsmoothed average dopamine signals from experiment 1 (mean ± S.E.M.) recorded during ‘valid’ Go trials (post-cue RT < 1.7 s; blue filled line) or ‘delayed’ Go trials (post-cue RT > 1.7 s; dotted cyan line) (NB: delayed Go trials were not included in any other analyses) aligned to either (a) cue onset or (b) time of head exit from nose-poke. Lower panels show average discriminability between the Valid and Delayed Go trials for each timepoint (shaded area = population of 1000 permuted sessions; line: *, p < 0.05 permutation tests, corrected for multiple comparisons). (c) Boxplot of the nose-poke holding times (central mark is the median, the edges of the box are the 25th and 75th percentiles, the whiskers extend to the most extreme data points) for the valid or delayed Go trials (*, p = 0.02, W7= 0, Wilcoxon Signed Ranks Test)
