Components of the neuronal dynamics determining RTs and correct-stop trials. (A) Projections on the PEA of the neuronal trajectories (direction 1)—namely, PEA activity—grouped by RTs (no-stop trials in deciles and wrong-stop trials in tertiles) or SSDs (correct-stop trials). After an initial period around the Go signal in which trajectories are overlapped, no-stop and wrong-stop trial projections diverge from correct-stop trials projections. (B) Projections on the HPA of the same neuronal trajectories—namely, HPA activity—as above; in this case, the projections display an initial ramp-like dynamics and similar features for all trials and conditions.
