声音传入内耳,引起基底膜的振动,致使毛细胞兴奋,听神经开始向中枢传入冲动,同时产生耳蜗电位。此电位可反映耳蜗的机能状态。自1930年Wever及Bray发现动物耳蜗电位以后,人们利用动物做了大量实验,收集了许多资料。其后,也有一些医务工作者试图记录病人的耳蜗电位,但限于当时的技术条件,如不经过手术将电极放于园窗或其附近,就不能收到效果。近年来,由于电子计算技术被引用到医
Sound into the inner ear, causing the basement membrane vibration, resulting in hair cells excited, the auditory nerve began to impulse into the center, while producing cochlear potential. This potential reflects the functional status of the cochlea. Since Wever and Bray discovered the animal’s cochlear potential in 1930, a great deal of experiments have been done with animals and many data have been collected. Since then, some medical workers have also tried to record the patient’s cochlear potential. However, due to the technical conditions prevailing at that time, no effect could be obtained if the electrode was placed at or near the circular window without surgery. In recent years, electronic computing technology has been cited as a doctor
