2 The majority of GABA A receptors expressed in the CNS are Î± 1 Î² 2 Î³ 2; with Î± 3 Î² 3 Î³ 2 and Î± 2 Î² 3 Î³ 2 receptors also highly prevalent (Fig-ure 2c). 11 GABA binds at the junction between subunits Î± and Î², whereas benzodiazepines bind at the interface between subunits Î± and Î³ (Figure 1b).
