Mean firing rates of the winning population. A, Mean firing rates for the winning populations of the next trial: in blue the post-correct case and in orange the post-error one. The ribbons represent the 95% confidence interval on 25 simulations(bootstrap method). The left-axis represents the relaxation of the dynamics. The right-axis is for the beginning of the next stimulus. The parameters are set to a region with PES effects (ICD = 0.035 nA and c = ± 10). Inset with the light blue curve is the difference between the post-error firing rates and the post-correct with respect to time (percentage). The ribbon stands for the 95% confidence interval. As expected, this difference is negative. Hence the post-correct dynamics is faster and crosses sooner the threshold. This leads to the PES effect. B, Mean synaptic activities for the winning populations of the next trial: in blue the post-correct case and in orange the post-error one. Inset with the light blue curve is the difference between the post-error synaptic activities and the post-correct with respect to time (percentage).
