Sensory expectations shape neural population dynamics in motor circuits

This study shows that sensory expectations influence motor preparation and corrective responses in humans and monkeys, with neural activity scaling with perturbation probabilities.

Pupil diameter tracked during motor adaptation in humans

This study tracks pupil diameter during motor adaptation in humans to assess internal states like surprise and environmental uncertainty, finding distinct patterns for tonic and phasic pupil responses.

Spinal stretch reflexes support efficient control of reaching

The paper shows spinal circuits can efficiently control hand movement during reaching, challenging the idea that supraspinal regions are solely responsible for such control.

Structure of population activity in primary motor cortex for single finger flexion and extension

The paper compares fMRI and electrophysiological data to explore how primary motor cortex organizes activity for finger flexion and extension, finding similar patterns for same-finger movements but distinct patterns in monkeys.

Spinal stretch reflexes exploit musculoskeletal redundancy to support postural hand control

The paper shows that spinal stretch reflexes adjust based on hand displacement relative to a target, not muscle stretch, demonstrating efficient motor control through musculoskeletal redundancy.

Rapid feedback responses are flexibly coordinated across arm muscles to support goal-directed reaching

The paper shows that rapid feedback responses in arm muscles adapt to visuomotor transformations, supporting goal-directed reaching through flexible coordination.
