Parkinson disease is the result of decreased levels of theneurotransmitter dopamine in the brain. However, thesepatients can’t take dopamine in drug form because the drugcannot reach the brain. What anatomic structure preventsthe drug from reaching the brain? How could these sameanatomic structures be beneficial to an individual underdifferent circumstances?
