Optimal control is a way of understanding motor control and the motor equivalence problem, but as with most mathematical theories about the nervous system, it has limitations.
2.
This consistency is referred to as motor equivalence and is important, says Wing, because it suggests that actions are encoded in the brain in terms more abstract than commands to specific muscles.
3.
Therefore, the " degrees of freedom problem " may be a misnomer and is better understood as the " motor equivalence problem " with redundant DOFs offering an evolutionary solution to this problem.
