(GABA is the main inhibitory neurotransmitter in the mammalian brain, which means it helps to regulate and quiet cellular activity.) While it remains unclear how, exactly, these chemical tweaks produce the psychological changes triggered by a beer or bourbon, a new study by researchers at the University of Pittsburgh (along
