一、诱发电位的概念诱发电位(Evoked Potential,EP)是指人工刺激所引起的中枢神经系统的电位变化。根据人工剌激和诱发电位的关系把诱发电位分为特异性诱发电位和非特异性诱发电位。非特异性诱发电位是指各种不同的刺激均能引起相同的诱发电位。比如用声和光的刺激均可引起自发脑电中的α波减弱或抑制。特异性诱发电位是指与刺激信号有严格关系的诱发电位,即在特
First, the concept of evoked potential Evoked potential (Evoked Potential, EP) refers to the artificial stimulation caused by changes in the central nervous system potential. According to the relationship between artificial stimulation and evoked potentials, evoked potentials are divided into specific evoked potentials and nonspecific evoked potentials. Non-specific evoked potential refers to a variety of different stimuli can cause the same evoked potentials. Such as the use of sound and light stimulation can cause spontaneous EEG wave attenuation or inhibition. Specific evoked potentials refer to evoked potentials that are strictly related to the stimulus signal, ie, are specific
