一般的简短刺激如短声、纯音和简单言语声均可诱发出听皮层诱发电位(auditory-evoked po-tentials,AEPs)的P1、N1和P2成分,由于P1的幅值相对较小,因此N1和P2波通常被认为是AEPs的特征波,通常将其归为N1/P2复合波。N1波对刺激声的起始特征敏感,P2波则反映了刺激声的声学或语音学 General brief stimuli such as short tone, pure tone and simple speech can induce P1, N1 and P2 components of auditory-evoked po-tentials (AEPs). Because P1 has a relatively small amplitude, N1 And P2 waves are generally considered characteristic waves of AEPs, which are usually classified as N1 / P2 complexes. The N1 wave is sensitive to the onset characteristic of the stimulus sound and the P2 wave reflects the acoustics or phonetics of the stimulus sound
