Question

Quizplus · Accepted Answer

The basal ganglia is the structure whose abnormal function is associated with Parkinson's disease. Specifically, loss of dopaminergic neurons in the substantia nigra, which provide input to the basal ganglia, is a hallmark of Parkinson's disease. This results in a decrease in dopamine levels in the basal ganglia, leading to the characteristic motor symptoms of the disease.
