A sudden change in dynamics produces large errors leading to increases in muscle co-contraction and feedback gains during early adaptation. We previously proposed that internal model uncertainty drives these changes, whereby the sensorimotor system reacts to the change in dynamics by upregulating stiffness and feedback gains to reduce the effect of model errors. However, these feedback gain increases have also been suggested to represent part of the adaptation mechanism. Here, we investigate… Expand


Visuomotor feedback gains upregulate during the learning of novel dynamics
This work investigates whether the sensorimotor control system alters feedback gains during adaptation to a novel force field generated by a robotic manipulandum and suggests that these feedback gains are upregulated with increased uncertainty in the knowledge of the dynamics to counteract any errors or disturbances and ensure accurate and skillful movements.

Time course of changes in the long latency feedback response parallels the fast process of short term motor adaptation
It is found that the long-latency feedback response (LLFR) was upregulated in the early stages of learning and was correlated with the fast component of feedforward adaptation, which suggests both are supported by common neural circuits. Expand
The Temporal Evolution of Feedback Gains Rapidly Update to Task Demands
Recent theoretical frameworks such as optimal feedback control suggest that feedback gains should modulate throughout a movement and be tuned to task demands. Here we measured the visuomotor feedbackExpand
Contributions of the motor cortex to adaptive control of reaching depend on the perturbation schedule.
TMS of M1 appeared to reduce adaptation of motor commands during a specific phase of learning: when motor commands tended to repeat. Expand
Increasing muscle co-contraction speeds up internal model acquisition during dynamic motor learning
Results show that muscle co-contraction accelerates the rate of dynamic motor learning, as measured by surface electromyography, and adaptation. Expand
Fractionation of the visuomotor feedback response to directions of movement and perturbation
This work demonstrates that feedback gains can be simultaneously tuned (upregulated and downregulated) depending on the state of the body and the environment. Expand

The investigation of how the CNS learns to control movements in different dynamical conditions, and how this learned behavior is represented, suggests that the elements of the adaptive process represent dynamics of a motor task in terms of the intrinsic coordinate system of the sensors and actuators.

Reductions in muscle coactivation and metabolic cost during visuomotor adaptation.
The results demonstrate that subjects modulate muscle activity, coactivation, and metabolic cost similarly across different forms of motor adaptation, suggesting that minimization of error and effort may be a general process underlying various forms of Motor adaptation. Expand
Rapid Feedback Responses Correlate with Reach Adaptation and Properties of Novel Upper Limb Loads
A novel paradigm requiring that human subjects adapt to a viscous elbow load while reaching to three targets highlighted an important link between the adaptation of feedforward and feedback control and suggest a key part of motor adaptation is to adjust feedback responses to the requirements of novel motor skills.

Preparing to Reach: Selecting an Adaptive Long-Latency Feedback Controller
It is wondered whether, during the preparatory period before the reach, the brain engaged this feedback controller in anticipation of the upcoming movement, and if so, its signature might be present in how the motor system responds to perturbations in the Preparatory period. Expand
