1 The atypical behaviour of GABAergic drugs in cultures pretreated with BDNF depended on changes in the anion reversal potential because (i) increases in extracellular Cl(-) concentrations abolished the neurotoxic action of muscimol; (ii) muscimol stimulated (36)Cl(-) efflux after pretreatment with BDNF; and (iii) exposure to BDNF reduced the expression of the neuronal K(+)/Cl(-) co-transporter, KCC2. Muscimol brain derived neurotrophic factor Mus musculus
