Signal-dependent noise determines motor planning


Christopher M Harris & Daniel M Wolpert

Christopher M Harris & Daniel M Wolpert (1998)


The authors present a unifying theory of eye and arm movements based on the single physiological assumption that the neural control signals are corrupted by noise whose variance increases with the size of the control signal. They propose that in the presence of such signal- dependent noise, the shape of a trajectory is selected to minimize the variance of the final eye or arm position
