To the beginner it provides an excellent introduction to the subject. To the expert it presents a coherent review of current knowledge and areas of uncertainty. What is abundantly clear is how much more remains to be discovered about how man controls movement. The stimulus provided by this volume will be invaluable to thought and experiment.
