What neurotransmitter acts as a neuro inhibitor and is commonly used to treat anxiety?

GABA, or gamma-aminobutyric acid, is a neurotransmitter that serves as the primary inhibitory neurotransmitter in the central nervous system. Its main function is to reduce neuronal excitability throughout the nervous system, leading to a calming effect. This characteristic makes GABA crucial in the regulation of anxiety, as it helps to balance the neural activity that may contribute to feelings of anxiety and stress.

In clinical settings, medications that enhance the effects of GABA, such as benzodiazepines, are commonly prescribed to manage anxiety disorders. By increasing GABA activity, these medications help to promote relaxation and reduce the symptoms associated with anxiety, making GABA an important target in the treatment of these conditions.
