为研究高级中枢对耳蜗微机制的调控作用，对正常人16例（32耳）进行有和无视觉选择任务条件下的畸变产物耳声发射（DPOAE）测试。结果显示视觉任务出现时DPOAE幅值下降，F2为1、2kHz处的DPOAE幅值下降达显著性水平（P＜0．05）。讨论了调控作用的可能机制。认为研究高级中枢和橄榄耳蜗传出神经系统对耳蜗功能的影响将有十分重要的生理和病理意义。
In order to study the regulation of the cochlear micromechanisms by the high center, 16 patients (32 ears) with normal subjects were tested for distortion product otoacoustic emissions (DPOAE) with or without visual selection. The results showed that DPOAE amplitude decreased when visual task occurred, and F2 decreased to a significant level at 1 kHz (P <0.05). Discussed the possible mechanism of regulation. That the study of the central nervous system and olfactory olfactory cochlear nervous system on the cochlear function will have a very important physiological and pathological significance.
