作者用听力正常的白色豚鼠,蜗外刺激使用银球电极,刺激耳蜗底转;鼓阶刺激应用100μm钽丝,电极深入圆窗3 mm。均用EABR进行观察。结果:(1)两者所反应的波形相同。(2)随着刺激电压的增大,潜伏期缩短,两者间无何差异。(3)各波的潜伏期,两者亦无差异。(4)诱发电位最初记录到的负波和随之出
The authors used white guinea pigs with normal hearing to stimulate the cochlear gyrus using a silver ball electrode to stimulate the bottom of the cochlea. The drum was stimulated with 100 μm tantalum wire and the electrode was deep into the round window 3 mm. All were observed with EABR. Results: (1) The two waveforms are the same. (2) As the stimulation voltage increases, the incubation period shortens, no difference between the two. (3) The incubation period of each wave, there is no difference between the two. (4) Initially recorded evoked potentials are followed by negative waves
