成年小型猪脑电图正常模式的研究

The electroencephalogram and brain electrical activity mapping patterns in Chinese experimental mini pigs

目的:为获得中国实验小型猪(CEMP)正常脑电图参考数据。方法:麻醉下,对CEMP行头皮电极描记额叶、颞叶、顶叶、枕叶的脑电图(EEG)波型并进行了两两样本间的t检验分析。结果:麻醉状态下CEMP的EEG模式以δ波为主,其时间指数为44%～75%,θ波时间指数为5%～32%,并经二次处理得出其脑电地形图(BEAM)。结论:CEMP具有可以重复描记出的脑电活动,故可以将其用于神经系统疾病模型的研究,本实验研究结果可以作为该动物麻醉状态下的正常脑电活动的参考。

Objective： To acquire normal patterns of EEG in Chinese experimental mini pigs （CEMP）. Methods： The EEGs at anesthetic state were recorded in 27 CEMPs. Results： The normal patterns of EEG in CEMPs at anesthetic state were similar to the humanity during sleep. Conclusions： The CEMP owns normal and recordable electric activity in the brain, so they are candidates for the neuroscience study.
