What role does dopamine play in motor control?
A) Dopamine binds receptors in the cerebral cortex to activate upper motor neurons to produce coordinated and smooth movements.
B) Dopamine enhances the process of motor learning in the cerebellum to reduce motor error.
C) Dopamine binds receptors on the caudate nucleus and putamen, inhibiting the globus pallidus. The upper motor neurons are eventually activated.
D) Dopamine inhibits the substantial nigra of the basal nuclei and inhibits the upper motor neurons from initiating movement.

Question

Quizplus · Accepted Answer

Dopamine binds to receptors in the caudate nucleus and putamen, which are part of the basal ganglia, leading to the inhibition of the globus pallidus. This process facilitates the activation of upper motor neurons, contributing to the initiation and regulation of movement.
