在高等哺乳动物,大脑皮层是中枢神经系统中最大和最容易接近的部分。将电极穿过动物颅骨插入大脑皮层表面,所记录到的电位变化即为动物脑皮层电图(ECoG)。在毒理学实验中,记录大鼠的脑皮层电图,观察毒物对大鼠脑皮层电活动的影响,对于阐明中枢神经系统高级部位机能障碍与脑
In higher mammals, the cerebral cortex is the largest and most accessible part of the central nervous system. Insert the electrode through the skull of the animal into the surface of the cerebral cortex. The potential change recorded is the ECoG. In toxicology experiments, the rat cortical electrograms were recorded to observe the effects of poisons on the electrical activity of the cerebral cortex in rats, to clarify the high level of the central nervous system dysfunction and brain
