Conventions as in Fig. 3. a Average spike rate and recruitment through time of neurons with persistent activity on canceled relative to latency-matched no-stop-signal trials. b Time–depth plot. c Modulation on successfully canceled relative to latency-matched no-stop-signal trials for shorter and longer Ttone of two representative neurons: n1 had narrow spikes in L3; n2 had broad spikes L3. Spiking of both neurons decreased after the tone. Shaded interval highlights significant differences in spiking across conditions. d Model comparison table for post-SSRT activity. Variation of spiking was best predicted by the surprise model S(t)Subjective, SS seen. Full statistics are in Supplementary Table 5. e Significant variation of spiking activity after SSRT as a function of S(t)Subjective, SS seen with 54 neurons contributing 162 samples across early, intermediate, or late Ttone. For 9 neurons no reliable estimate of spike density for the late-SSD bin was obtained due to too few trials. These data points were not included.
