Question

Quizplus · Accepted Answer

Parkinson's disease is caused by the degeneration of neurons in the basal ganglia, a group of nuclei located deep within the brain that are responsible for the control of movement. Damage to these neurons leads to a decrease in dopamine production, resulting in problems with initiating voluntary movements. The amygdala is involved in emotion and memory processing, the cerebral cortex is responsible for higher cognitive functions such as perception and thought, and the cerebellum is important for coordinating movement and maintaining balance, but none of these structures are directly involved in Parkinson's disease.
