Other aspects of motor control

My view on motor control is that it consists of several more or less independent levels of description. Motor behaviour is in my view mainly shaped by the requirements of the task, combined with a general tendency to smooth (damped mass-spring like) behaviour. This is why mass-spring models and the minimum jerk model are so successful in describing behaviour (see also my work on interception and prehension) One level below is the description at the level of muscles and joints (see my publications up to 1995 in the list below). The question at this level is how the nervous system activate the muscles in such a way that the task-determined behaviour emerges. Muscle co-ordination, reflexes, degrees of freedom, and interaction torques are terms that are important at this level of description. These properties are in healthy adult humans not important for the shape of behaviour: the nervous system is able to deal with them to yield optimal skilled behaviour. The two levels interact only when the limits of the nervous systems capabilities are reached in a task. This occurs more frequently in patients.
