Question

Quizplus · Accepted Answer

In Parkinson's disease, the basal ganglia have too much output and are too sensitive to input. This is primarily due to the loss of dopamine-producing cells in the substantia nigra, a part of the basal ganglia, which normally helps modulate movement and coordination. The imbalance leads to the motor symptoms characteristic of Parkinson's disease, such as tremors, stiffness, and difficulty initiating movements.
