Step-by-step explanation:
True Statement: All of the above options are true.
The correct answer is option 4) All of the above.
Deep brain implant surgery is indeed done on awake patients. This type of surgery is used to treat neurological disorders such as Parkinson's disease. The patient is awake during the surgery so that the surgeon can accurately target the specific region of the brain for implantation.
In Parkinson's disease, the substantia nigra region of the brain does die. This region is responsible for producing dopamine, a neurotransmitter that plays a crucial role in movement control. The death of cells in the substantia nigra leads to a decrease in dopamine levels and the development of Parkinson's disease symptoms.
Approximately 50,000 Americans are indeed diagnosed with Parkinson's disease each year. Parkinson's disease is a common neurodegenerative disorder that affects a significant number of people, primarily older adults.
