We wanted to determine whether behavioural and GABAergic functional deficits induced by the NMDA receptor channel blocker , phencyclidine ( PCP ) , could be reversed by repeated administration of two drugs known to enhance GABAergic transmission : the positive allosteric modulator ( PAM ) of the metabotropic glutamate receptor 5 ( mGluR5 ) , ADX47273 , and the partial agonist of the alpha 7 nicotinic acetylcholine receptor ( alpha 7 nAChR ) , SSR180711 .
