Learning feedback and feedforward control in a mirror-reversed visual environment.
When we learn a novel task, the motor system needs to acquire both feedforward and feedback control. Currently, little is known about how the learning of these two mechanisms relate to each other. In the present study, we tested whether feedforward and feedback control need to be learned separately, or whether they are learned as common mechanism when a new control policy is acquired. Participa...

متن کاملStructural learning in feedforward and feedback control.
For smooth and efficient motor control, the brain needs to make fast corrections during the movement to resist possible perturbations. It also needs to adapt subsequent movements to improve future performance. It is important that both feedback corrections and feedforward adaptation need to be made based on noisy and often ambiguous sensory data. Therefore, the initial response of the motor sys...
متن کامل' & $ % Iterative Learning Control Using Optimal Feedback and Feedforward Actions
An algorithm for Iterative Learning Control is developed based on an optimization principle which has been used previously to derive gradient type algorithms. The new algorithm has numerous bene ts which include realization in terms of Riccati feedback and feedforward components. This realization also has the advantage of implicitly ensuring automatic step size selection and hence guaranteeing ...
متن کاملFeedforward and feedback processes in motor control.
In this study, we utilized functional magnetic resonance imaging (fMRI) to examine which brain regions contribute to feedback and feedforward motor control processes. Several studies have investigated the contributions of cortical and subcortical brain regions to motor performance by independently varying factors such as movement rate, force, and speed, and observing the neural responses. Such ...
