Isotonic task modeling. a Motoneuron firing rate normalized to its maximum and feedback normalized to its maximum in simulated response to increasing supraspinal input with no feedback and force feedback (strength = 0.4). Color code is the same for all panels. b Average normalized force as a function of the central input. Solid lines indicate linear fits obtained in the two cases for inputs > 2. The titles report quality of the linear fitting (R2). c Average (and standard deviation) of the single unit responses as a function of central input for the two feedbacks. The standard deviation for the five units is so close to the average that lines cannot be discriminated. d Peak of normalized firing rate as function of resulting force in models. Markers indicate different trials for no feedback (squares), and force feedback (diamonds). Solid lines indicate fits obtained in the two cases with Eq. (9). Title reports fit quality. e Average normalized response for the simulated feedbacks as a function of the normalized force. Solid lines indicate obtained fits in the two cases with Eq. (9). Title reports fit quality for the two cases
