Methods: Totally 16 healthy adult rabbits of both sexes were randomly divided into SP group and NS group. The rabbits in SP and NS group were given Thiopental (3 mg/kg) and normal saline (1 ml/kg) respectively by intravenous injection via ear vein after establishing convulsant models by injecting Strychnine into the other ear vein. QPEEG and power spectral analysis were used to analyze the changes of δ-band of QPEEG in convulsant rabbits before and after administering drugs.
