"Method eight adult rabbits, male and female informal, in the seizure occurred immediately after the rabbit ear intravenous thiopental, application QPEEG, using power spectral analysis, analysis of rabbits seizures before and after the intravenous injection of thiopental QPEEG δ, θ, α1, α2, α3, β six band changes. The results compared with the previous administration, δ band power at 2 min percentage was higher (p <), 20min later reduced to normal. θ band 1 min-20min when the percentage of significant power Lower (p <), 20min after the return to normal. Α-band power percentage decline in 5 min, the most obvious (p <), 10min started to recover, 20 min returned to normal levels. Β band of power when the percentage of 2 min dropped the most obvious ( p <), 10min resume at a normal level, then continued the upward trend (p <). thiopental conclusion of strychnine significant seizures of antagonism, θ band changed most significantly, tips can be used as convulsions, Brain wave monitoring the observation of the major indicators and thiopental anticonvulsant when the target amount. Β band activities were excited after the first curb the phenomenon, the use of thiopental to speculate on the body may have a cerebral cortex "easy" effect. "
