Quizplus · Accepted Answer

GABA (gamma-aminobutyric acid) is an inhibitory neurotransmitter that is believed to reduce anxiety reactions by slowing down or inhibiting nerve impulses in the brain. Low levels of GABA have been associated with anxiety disorders. The other neurotransmitters listed (dopamine, serotonin, and norepinephrine) are not typically considered to be directly involved in reducing anxiety reactions, although they may play a role in related processes such as mood regulation or stress response.
