Abstract:
Aim To study the effects of a novel psychoactive drug,modafinil,on the GABAA receptor-induced current in rat hippocampus pyramidal neurons.Methods Whole-cell patch-clamp recordings were applied in cultured hippocampus pyramidal neurons.Results The GABA-activated currents were blocked by bicuculline,a competitive antagonist of GABAA receptor.Modafinil could partly inhibit IGABA.Pre-treating hippocampus neurons with glibenclamide for 30 min,modafinil-induced inhibition on IGABA was removed.Conclusion Modafinil is different from other psychostimulants.The protection of modafinil may be via modulating ATP sensitive potassium channel activation.
