(a) Significant correlation between BF bursting amplitude to the go signal and neuronal inhibition latency relative to SSRT in both SST variants. Results were plotted separately for individual BF bursting neurons (left, n=138, 104) and for sessions with at least 4 BF bursting neurons (right; n=24). (b) Significant correlation between peri-SSRT inhibition by the stop signal and neuronal inhibition latency relative to SSRT in both SST variants. (c-d) BF bursting neurons were sorted into five quintiles based on their peri-SSRT inhibition amplitude, separately for the two SST variants. The 1st quintile is shown in red/green, while the 5th quintile in gray. Average responses of each quintile (mean ± s.e.m.) to the go signal in go trials (c) and peri-SSRT inhibition in all stop trials (d). Bins showing significant inhibition around SSRT are labeled by horizontal lines for each quintile. BF neurons that were inhibited earlier relative to SSRT were inhibited more by the stop signal and excited more by the go signal. The red shaded areas indicate the 95% CI of SSRT estimate (n=17, 20 sessions).
