Figure 2GABABRs involvement in the tonic GABAA current of TC neurons in genetic and pharmacological models of typical absence seizures

A. Current traces form TC neurons of normal Wistar rat showing the GHB-elicited increase in tonic GABAA current and its block by the GABAB antagonists CGP55845 (10 μM). B. Comparison of the effects of different concentrations of GHB on tonic GABAA current amplitude in normal Wistar rats, and its block by CGP55845 (10 μM). Note how CGP55845 alone decreases tonic current amplitude compared to control conditions. Values are normalised to the average tonic current in the absence of GHB or CGP55845. C. Effect of bath application of 10 μM CGP55845 on tonic GABAA current in GAERS, stargazer (stg) and lethargic (lh) mice. Values are normalised to the average tonic current amplitude in the absence of CGP55845. B and C: * p<0.05, ** p<0.01 and *** p<0.001.
