A proportion of the tonic GABAA current in hippocampal interneurons is independent of vesicular GABA release. (A) Representative traces showing picrotoxin (PTX)-sensitive tonic current in a control slice and a slice treated with bafilomycin A1 (Baf. A1); black line—PTX application. (B) Mean Ispont in control (n = 14) and bafilomycin A1-treated slices (n = 6). (C) Mean tonic GABAA current (ΔIhold, n = 14) in control and bafilomycin A1-treated slices (n = 6). *P < 0.05, **P < 0.01, unpaired t-test.
