The effect of oxysophoridine on electric activities and its power spectrums of cerebral frontal cortex in rats

Aim To observe the effect of oxysophori-dine( OSR) on the EEG changes and its power spectrums of cerebral frontal cortex in anaesthetized rats. Methods With the equipment of brain stereotactic apparatus,electrode was implanted into frontal lobe of cerebral cortex in rats. Unipolar lead and computerized FFT technique were employed to record the index of EEG,power spectrum and frequency distribution…
