This study investigates subcortical control of reaching in humans using a visuomotor task, finding coordinated muscle responses that suggest subcortical systems can compute musculoskeletal dynamics for reaching.

This study investigates neural control signals during reaching by isolating express and voluntary responses, revealing alternating excitation and inhibition in muscle activity and corticospinal excitability.

The paper investigates the origin of rapid corticospinal excitability changes during visually guided reaching and finds subcortical, not cortical, modulation of motor evoked potentials.

The paper shows that symbolic cues modulate express visuomotor responses in human arm muscles, suggesting motor plan-level modulation rather than early visuospatial processing.

The paper investigates how symbolic and barely detectable cues modulate express visuomotor responses, showing both top-down and bottom-up influences on a subcortical network.

This study investigates how temporal predictability affects express visuomotor responses, finding that predictable target timing enhances the frequency and strength of stimulus-locked responses.

The paper investigates rapid recalibration of temporal order judgements and finds that response bias, not timing perception, explains contradictory results.
