Model of the -Aminobutyric Acid (GABA) Receptor Forming a Chloride Channel

(From Mohler H, Richards JG. The benzodiazepine receptor: a pharmacologic control element of brain function. Eur J Anesthesiol Suppl. 1988;2:15-24, with permission.)

Benzodiazepines (benzo) attach selectively to subunits and are presumed to facilitate the action of the inhibitory neurotransmitter GABA on subunits.
