摘　　要：研究在鼓阶或前庭阶记录由频谱复合音诱发的耳蜗电位,应用微机化生理药理实验教学系统,对幼龄豚鼠耳蜗的不同声音刺激予以记录分析。实验结果表明持续声短纯音诱发耳蜗电位CM与CAP重叠;而脉冲短声诱发耳蜗电位的CM与CAP分离。并对频谱复合音的振幅与微音电位(CM)、听神经复合电位(N1,N2)的关系进行了深入探讨,发现刺激频率的振收稿日期:2002-06-15作者简介:彭中进(1981-),男,江苏南通人,南通师范学院生命科学与技术系学士在读。幅Amp是负值时听神经复合电位N1与N2随Amp的增加而降低。The cochlear potentials to the frequency complex tones recorded from the scala tympani or scala media were studied in this paper.The different sounds stimulation of young guinea pigs cochlear were recorded by applying the microcomputer physiological and pharmacological experimental teaching system.The results indicated that the microphonic potential and the compound action potential overlapped to the continued sounds short pure tone .The microphonic potential was separated from the compound action potential by the pulse short tone .The relationship between the amplitude of the frequency complex tones and the microphonic potential ,the compound action potential (N1,N2) were deeply probed,When the amplitude of stimulate frequency was negative,the compound action potential N1 and N2 were dropped with the amplitude increasing .
