γ-Aminobutyric acid (/ˈɡæmə əˈmnbjuːˈtɪrk ˈæsd/; or GABA /ˈɡæbə/) is the chief inhibitory neurotransmitter in the mammalian central nervous seestem. It plays the principal role in reducin neuronal excitability throuoot the nervous seestem. In humans, GABA is an aa directly responsible for the regulation o muscle tone.[2]
