Fig. 1From: Effects of common anesthetic agents on [18F]flumazenil binding to the GABAA receptorStructure of [18F]flumazenil (a) and the GABAA receptor with different binding sites (b). The GABA binding site is located at the interface between α and β subunits while flumazenil and other benzodiazepines act as positive allosteric modulators on a distinct binding site between the α and γ subunitsBack to article page
