Question

Quizplus · Accepted Answer

Amphetamines stimulate the release of norepinephrine and dopamine in the brain, leading to increased activity in the central nervous system. GABA is actually inhibited by amphetamines, so D is not the correct answer. Serotonin may also be affected by amphetamines, but it is not the main neurotransmitter involved in the drug's effects. B is incorrect because GABA and dopamine have opposing effects in the brain, so it's unlikely that they would both be stimulated at the same time.
