Within the thalamus, the ventral anterior (VA) nucleus is specifically involved in the induction, execution, and control of aspects of voluntary movement.1

Additionally, the ventral lateral (VL) nucleus plays a role in balance and fine motor control. Together, these motor nuclei serve as relay stations that receive input from the basal ganglia and the cerebellum, projecting to the primary motor area, the premotor cortex, and the supplementary motor area to coordinate the force, sequence, and direction of motor activities.12
