为探讨豚鼠听觉中枢对畸变产物耳声发射（DPOAE）的影响，利用土的宁阻断听觉系统的传出神经，系统观察了阻断前后DPOAE的变化。结果发现在本实验条件下，所有豚鼠均可引出DPOAE，在同等刺激强度和L1-L2的情况下，低频f0=1006HZ的DPOAE强度大，而较高频f0=2011和f0=4033的DPOAE强度较小。土的宁阻断橄榄耳蜗束对DPOAE无影响，提示在正常神经张力下中枢不参与、不影响DPOAE的产生和形成。 To investigate the influence of auditory center of guinea pig on distorted product otoacoustic emissions (DPOAE), we use Turanin to block the afferent nerves of auditory system and systematically observe the changes of DPOAE before and after the blockade. The results showed that under the experimental conditions, all of the guinea pigs could induce DPOAE. Under the same stimulus intensity and L1-L2 condition, the DPOAE intensity at low frequency f0 = 1006HZ was large, while that at higher frequency f0 = 2011 and f0 = 4033 Smaller. Tu Ning Ning block olives cochlear bundle has no effect on DPOAE, suggesting that under normal nerve tension does not participate in the center, does not affect the DPOAE generation and formation.
