SR 95103 has recently been described as a selective GABAA antagonist. In this study, the electroencephalographic (EEG) effects of SR 95103 were investigated as well as its central interaction with inhibitory amino acids and muscimol. Slow intravenous infusions of SR 95103 in rats induced epileptiform EEG activities which were antagonized by intracerebroventricularly injected muscimol, GABA and taurine whereas glycine did not modify and even facilitated the effects of SR 95103. These results suggest that the EEG effects of SR 95103 are due to the specific GABAA antagonistic properties of this compound.
