Question

Quizplus · Accepted Answer

This question describes the opposite effects of dopamine in two different neurological conditions, Parkinson's disease and schizophrenia. Parkinson's occurs due to a deficiency in dopamine, while schizophrenia occurs due to excess dopamine. Therefore, dopamine is the excitatory neurotransmitter responsible for both conditions. The other options, glutamate, acetylcholine, and serotonin, are not the primary neurotransmitters implicated in either of these conditions.
