8. Adaptations to Coriolis forces and robotic dynamic force fieldsmovement accuracy during Coriolis force occurs much more rapidly than it does during robotic perturbations

10. De-adaptation Re-adaptation

11. Coriolis forces and self-calibration In everyday behavior, very large Coriolis forces are generated on the arm during simultaneous turning and reaching for an object . the continuous, normal process of sensory–motor self-calibration

13. Spatial goals and adaptation to jaw and limbperturbations spatial goal dependency Pointing movements Particular speech sounds

14. Consolidation of motor learning The use of robotic manipulanda to perturb movements has generated considerable interest in what is being learned and how it is being learned .

15. Internal models of motor control

16. Adapting to multiforce perturbations An important unanswered question is whether adaptation to a robotic device will influence self-calibration of unfettered movements or will be specific to contexts including contact.

17. Neurophysiological studies of motor control ♦ separate populations of neurons encode the dynamic and the postural components of a movement . ♦ neurons in area M1 participate in a variety of motor tasks that involve different constraints .
