Motor control is the study of how organisms make accurate goal-directed movements. Here
we consider two problems that the motor system must solve in order to achieve such control. …

We investigated how the CNS learns to control movements in different dynamical conditions,
and how this learned behavior is represented. In particular, we considered the task of …

The cerebellum is an essential part of the neural network involved in adapting goal-directed
arm movements. This adaptation might rely on two distinct signals: a sensory prediction …

Previous research has demonstrated that the primate CNS has the ability to learn and store
multiple and conflicting visuo-motor maps. Here we studied the ability of human subjects to …

LEARNING a motor skill sets in motion neural processes that continue to evolve after practice
has ended, a phenomenon known as consolidation 1–4 . Here we present psychophysical …

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, we …

The study of patients to infer normal brain function has a long tradition in neurology and
psychology. More recently, the motor system has been subject to quantitative and computational …

an Internet search for the text string "Reza Shadmehr Home Page" should lead you to these …

Computational studies suggest that acquisition of a motor skill involves learning an internal
model of the dynamics of the task, which enables the brain to predict and compensate for …

Multiple processes may contribute to motor skill acquisition, but it is thought that many of
these processes require sleep or the passage of long periods of time ranging from several …
