(a) The entropy production rate (EPR) versus motion input strength μ0. The decision time represented by the MFPT versus input strength μ0 is shown with the red line. (b) The total energy cost versus motion input strength μ0. (c) The total energy cost increases as the decision time increases. For fast (slow) decisions, the performance can be improved with decreasing (increasing) decision time. Here the accuracy is represented by the ratio of the probability of the path of the correct choice to that of the error one. (d)–(f) The inter-relationship among the speed, accuracy, and energy cost based on presenting additional input to cortical integrators. In all subgraphs, parameters a = 269.5, b = 108, c′ = 0.24, and D = 3.6 × 10−7.
