HOW DO NEURONAL AND MUSCLE-MECHANICAL PROPERTIES CONTRIBUTE TO THE PERFORMANCE OF THE DELTA-LOGNORMAL MODEL

Plamondon & Alimi's model will gain substantially in credibility when it is able to come up with predictions for new (rather than old) exper imental results that discriminate between various models. Moreover, th e present model is nothing more than a descriptive ''black box,'' not an explanation for motor performance. A link to the contribution of va rious neuronal mechanisms involved in motor control and of muscle prop erties to the performance of the model is crucial.
