家兔常规定量脑电图的描记

Quantitative electroencephalography of conscious rabbit

目的建立清醒状态下家兔定量脑电图(BEAM)的描记方法。方法用CFM-8型21导数字化EEG机记录126只家兔左、右脑的额、颞、顶、枕各区的BEAM。结果用本方法可成功地记录清醒兔的BEAM。与正常成人EEG以α波为主、枕区能量最高不同,兔以θ频段分布最广泛,以顶区能量最高。此外,人的β频段也低于家兔。结论清醒状态下家兔BEAM稳定可靠,可作为研究药物定量脑电图的模型。

Aim To establish recording methods of quantitative brain electrical activity mapping （BEAM） of conscious rabbits. Methods The claw-shape needle electrodes were placed respectively on epicranium in the area of forehead, temporal bone, cupula and pulvinar of left and right brain , then CFM-8 digited electroencephalography was used for recording the EEG of twenty rabbits. Results The θ-brand was most widely distributed and the power in the area of occipital bone was the highest. Conclusion QEEG of conscious rabbit was stable and reliable. It provides a foundation for advanced researches into quantitative pharmaco-EEG.
