目的研究封闭群新西兰白兔颅外头皮脑电图(EEG)及颅内大脑皮质脑电图(ECoG)。方法对封闭群新西兰白兔进行颅外头皮脑电图及颅内大脑皮质脑电图描记,并比较、观察和分析两种方法的描记结果。结果 EEG以9~12c/s的α波及16~20 c/s的β波为基本节律,波幅为30~100μV;ECoG则以10~12c/s的α波及16~20 c/s的β波为基本节律,波幅为200~300μV;麻醉能使脑电活动减弱,脑组织缺氧,麻醉后ECoG以δ及θ慢波为主。结论 EEG测定方法简单,操作简便,家兔无需麻醉,无创伤,所描记的脑电波形与ECoG高度一致,可以替代传统的ECoG进行神经系统功能的研究。
Objective To study the extracranial scalp electroencephalogram (EEG) and intracranial cerebral cortex electroencephalogram (EEG) in a closed population of New Zealand white rabbits. Methods The closed head New Zealand white rabbits were subjected to extracranial scalp electroencephalography and intracranial cerebral cortex electroencephalography. The results of the two methods were compared and observed. Results EEG showed the basic rhythm of α wave of 9 ~ 12c / s and β wave of 16 ~ 20 c / s with the amplitude of 30 ~ 100μV. The ECoG showed the effect of 10 ~ 12c / s α wave and 16 ~ 20 c / As the basic rhythm, amplitude of 200 ~ 300μV; anesthesia can make EEG activity weakened brain tissue hypoxia, ECoG to anesthesia δ and θ slow wave based. Conclusion The method of EEG is simple and easy to operate. The anesthesia and noninvasive trauma of EEG in rabbits are highly consistent with ECoG, which can replace the traditional ECoG in the study of nervous system function.
