Answer:

Dopamine depletion in the substantia nigra.

Step-by-step explanation:

Parkinson's is characterized by a deterioration in dopamine production. Dopamine sends signals to the substantia nigra to inhibit unintentional movement (e.g., resting tremor). Therefore, a lack of dopamine in the substantia nigra causes a resting tremor.
