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 …

Primary motor cortex (MI) plays an important role in voluntary motor behaviour, yet
considerable debate remains on how neural processing within this brain region contributes …

Synergy discusses a general problem in biology: The lack of an adequate language for
formulating biologically specific problems. Written for an inquisitive reader who is not …

Neurons in monkey primary motor cortex (M1) tend to be most active for certain directions of
hand movement and joint-torque loads applied to the limb. The origin and function of these …

Motor training with the upper limb affected by stroke partially reverses the loss of cortical
representation after lesion and has been proposed to increase spontaneous arm use …

Corrective responses to limb disturbances are surprisingly complex, but the neural basis of
these goal-directed responses is poorly understood. Here we show that somatosensory …

A gain field, the scaling of a tuned neuronal response by a postural signal, may help support
neuronal computation. Here, we characterize eye and hand position gain fields in the …

Many human studies have demonstrated that rapid motor responses (ie, muscle-stretch
reflexes) to mechanical perturbations can be modified by a participant's intended response …

The question of how the central nervous system coordinates redundant muscles has been a
long-standing problem in motor neuroscience. The optimization hypothesis posits that the …

Controlling motor actions requires online adjustments of time-varying parameters. Although
numerous studies have attempted to identify the parameters coded in different motor sites …
