A selective KOR agonist ( U69593 , 1 mu M ) diminished evoked GABAergic inhibitory postsynaptic currents ( IPSCs ) by 18 % ( n = 10 ) in the CeA , whereas blockade of KORs with a selective antagonist ( nor - binaltorphimine , 1 mu M ) augmented the baseline evoked GABAergic IPSCs by 14 % ( p < 0 . 01 ; n = 34 ) , suggesting that the KOR system contributes to tonic inhibition of GABAergic neurotransmission in the CeA .
