| summary | The human movement system has many more degrees of freedom (joints, muscles, motor-neurons) than strictly necessary for most movement tasks. Howexhaust does it harness these many components into a coherent pattern so solve particular motor tasks? The talk will review our approach based on the principle of the uncontrolled manifold, in which we look at the structure of variance to uncover structures of coupling that solve the degrees of freedom problem. Movement within the uncontrolled manifold (self-motion) will be shown to occur routinely in simple pointing tasks. The concept of an uncontrolled manifold also provides an account for motor equivalence, the recruitment of new solutions for a motor task when perturbations drive the system away from its standard solution. The talk will review both experiments and closely related theoretical modelling ideas around which the concepts have been developed. Experiments cover a wide range of motor skills including pointing, shooting, posture, and isometric finger force tasks. |
