Inputs and outputs

The ventral anterior nucleus receives neuronal inputs from the basal ganglia. Its main afferent fibres are from the globus pallidus. The efferent fibres from this nucleus pass into the premotor cortex for initiation and planning of movement.[2]


It helps to function in movement by providing feedback for the outputs of the basal ganglia.[3]
