Differential kinematic control and co-ordination among redundant joints during whole arm reaching movements

This study investigates how the central nervous system controls redundant joints during arm reaching, finding that proximal joints control task space while distal joints manage joint redundancy.

Kinematic signatures of fast feedback trajectory control during goal-directed finger, arm, and saccadic eye movements

The paper investigates whether goal-directed movements follow pre-planned trajectories or result from online control, finding evidence of early feedback control and varying controller gains during movements.

Motor learning in reaching tasks leads to homogenization of task space error distribution

This study shows that motor learning homogenizes task space error distribution during reaching tasks, reducing directional error dependence and improving control efficiency.

Basal ganglia contributions during the learning of a visuomotor rotation: effect of dopamine, deep brain stimulation and reinforcement

This study shows the basal ganglia contribute to visuomotor adaptation in Parkinson's patients, influenced by dopamine, deep brain stimulation, and reinforcement.
