Abstract The exploits of Martina Navratilova and Roger Federer represent the pinnacle of
motor learning. However, when considering the range and complexity of the processes that …

In order to generate skilled and efficient actions, the motor system must find solutions to
several problems inherent in sensorimotor control, including nonlinearity, nonstationarity …

Initiating a movement in response to a visual stimulus takes significantly longer than might
be expected on the basis of neural transmission delays, but it is unclear why. In a visually …

Humans are adept at performing an extraordinary breadth of voluntary motor actions that
allow us to rapidly move around and interact with the environment. While voluntary motor …

Optimal control theory and its more recent extension, optimal feedback control theory,
provide valuable insights into the flexible and task-dependent control of movements. Here …

Optimal feedback control (OFC) provides a powerful tool to interpret voluntary motor control,
highlighting the importance of sensory feedback in the control and planning of movement …

Following a change in the environment or motor apparatus, human subjects are able to
rapidly compensate their movements to recover accurate performance. This ability to adapt …

Neural activity in monkey motor cortex (M1) and dorsal premotor cortex (PMd) can reflect a
chosen movement well before that movement begins. The pattern of neural activity then …

A basic difficulty for the nervous system is integrating locally ambiguous sensory information
to form accurate perceptions about the outside world,,,. This local-to-global problem is also …

There has traditionally been a separation between voluntary control processes and the fast
feedback responses which follow mechanical perturbations (ie, stretch “reflexes”). However …
