D)Hyperactivity of metabolic enzymes that degrade dopamine
E)Natural tendency of basal nuclei to follow a daily recurring, oscillating cycle of rising and falling norepinephrine release

Question

Quizplus · Accepted Answer

Parkinson's disease is caused by the degeneration of dopamine-producing neurons in the substantia nigra. This leads to a reduced ability to release dopamine, which is crucial for the proper functioning of the basal ganglia, a group of brain structures that control movement. As dopamine levels decrease, motor symptoms like tremors, rigidity, and bradykinesia (slowed movement) occur.
