Question

Quizplus · Accepted Answer

The basal ganglia, which includes the substantia nigra and globus pallidus, is important for motor control and learning of various tasks, including operant conditioning. Parkinson's disease is characterized by the loss of dopamine-secreting neurons in the substantia nigra, which results in impairment of basal ganglia function and motor learning. Therefore, the deficits in Parkinson's disease that impair learning a visually cued operant conditioning task are associated with the basal ganglia.
