Researchers Believe That Dopamine Has an Important Role in Moving

Researchers believe that dopamine has an important role in moving because:

A) one of dopamine pathways is to the basal ganglia,which is extremely important organizing motor behaviors.
B) overactivity of dopaminergic synapses in frontal lobe have been found among patients with dyskinesia.
C) dopamine is widely distributed throughout the brain and plays a role to produce movement and behavior at each part of motor muscles.
D) dopamine forms predominantly among neurons in a brain stem called "locus cerules",where majority of movements are controlled.
