Cosine Tuning Minimizes Motor Errors

  title={Cosine Tuning Minimizes Motor Errors},
  author={Emanuel Todorov},
  journal={Neural Computation},
Cosine tuning is ubiquitous in the motor system, yet a satisfying explanation of its origin is lacking. Here we argue that cosine tuning minimizes expected errors in force production, which makes it a natural choice for activating muscles and neurons in the final stages of motor processing. Our results are based on the empirically observed scaling of neuromotor noise, whose standard deviation is a linear function of the mean. Such scaling predicts a reduction of net force errors when redundant… CONTINUE READING
