Which of the following is NOT among the four principal neurotransmitters important to counselors?

• A. Glycine
• B. Acetylcholine
• C. Serotonin
• D. Dopamine

Answer: (D)

In counselor education, certain neurotransmitters are highlighted because they map closely to common mental health processes: mood, arousal, memory, and movement. The four usually cited are acetylcholine, dopamine, serotonin, and norepinephrine. Glycine, while an important inhibitory neurotransmitter—especially in the spinal cord and brainstem— isn’t typically included in that core quartet. So glycine is the one that doesn’t belong with the four principal neurotransmitters emphasized for counselors. Dopamine, in contrast, is a key member of that standard group, involved in reward, motivation, and movement.
