定义我们知道,脑诱发电位是中枢神经系统在感受外或内在刺激过程中产生的生物电活动。脑的诱发电位是相对于脑的自发电位而言。脑电图反应的是大脑皮层在无外界刺激时产生的电活动,它的特点具有节律性和连续性。而脑诱发电位是代表中枢神经系统特定功能状态下的生物电活动的变化。概括地说,人的感觉器官如眼、耳、皮肤感受器在接受光、声或微弱电流等特定的诱发刺激后,循其特有的神经通路将所感觉的信息向中枢传递,其信息内容在通路的各个水平不断组合,最后到达皮层 Definition We know that brain evoked potentials are bioelectrical activities that the central nervous system produces during or outside the sensory stimulation. The evoked potential of the brain is relative to the spontaneous potential of the brain. EEG is the reaction of the cerebral cortex in the absence of external stimuli generated when the electrical activity, its characteristics are rhythmic and continuous. The brain evoked potentials represent changes in bioelectric activity in a specific functional state of the central nervous system. In a word, people’s sensory organs such as eyes, ears and skin receptors, after receiving specific stimuli such as light, sound or weak current, transmit their sensory information to the central nervous system through their unique neural pathways. The level of the continuous combination, and finally reach the cortex
