The most unusual thing about the neurotransmitter nitric oxide (NO) is that it is normally a poisonous gas. It is distinct from other neurotransmitters as it is a gas that can diffuse through cell membranes and is not stored in vesicles like other neurotransmitters. It is involved in many physiological processes including vasodilation, immune response, and neurotransmission.
