摘要
脑电图(EEG)是一种无创脑部电活动测量方法,通过在头皮处安放电极,描记大脑皮层神经细胞所产生的兴奋性和抑制性突触活动的总和.EEG可揭示不同大脑区域的功能及其复杂的相互作用.利用EEG解析麻醉药物在神经中枢的作用机制、判断麻醉深度已成为当前的研究热点.本文拟对EEG的连通性分析方法及其在麻醉药物研究中的应用进行综述,以期进一步探讨未来可能用于研究麻醉药物作用机制的脑电分析方法.
Abstract
Electroencephalography(EEG)is a noninvasive brain-activity measurement technique that uses electrodes placed on the scalp to record the bioelectrical activity of neurons in the cerebral cortex the sum of excitatory and inhibitory synaptic activity.EEG can reveal the function of different brain regions and the complex intercommunication.In recent years,many studies have focused on the use of EEG to ana-lyze the mechanism of general anesthetics and to measure the depth of anesthesia.The connectivity analysis methods of EEG are introduced and their application on anesthetic drugs are reviewed in order to explore other potential EEG analysis methods of drug action mechanism in the future.
