说明山弱噪声引起的耳蜗随机共振在_ _仁行传入过程中可能激活了至所一记录的jc神经元的gaba能抑制性神经回路，这种gaba能抑制为锐化神经元频率调谐提供了一种抑制性输入，使ic神经元对靠近最佳频率的频率分析变得更为细致和精确，由于声频率是声信号的重要参数和信息载体，频率调谐的锐化意味着对声频率分析能力增强，从而为解释人们为什么能从充满噪声的环境中捕捉或提取与行为学相关的信号提供了一种细胞水平的实验证据。 | | 5. | In order to study the effect of weak noise on the sound signal extraction of mouse ( mus musculus km ) inferior collicular ( ic ) neurons from environment , we examined the change in frequency tuning of neuron induced by a weak noise relative to 5 db below minimum threshold ( remt - 5 db ) of tone . 12 healthy adult mice ( 20 - 25 g , b . wt . )
本实验旨在探讨弱噪声对小鼠( musmusculuskm )中脑下丘( inferiorcolliculusic )神经元声信号提取的影响及其神经机制，我们选用相当于纯音阈下5db的白噪声( whitenoise ) ，比较加入噪声前后神经元频率调谐曲线的变化和注射-氨基丁酸( - aminobutyricacid ， gaba )能受体拮抗剂荷包牡丹碱( bicuculline ， bic )后对该变化的影响。 | | 6. | It showed that activated inhibition by weak noise could be gabaergic inhibition . from above the findings , we could give a hypothesis that the input of random oscillation induced by noise in the cochlea to central auditory system could be integrated in the central auditory nucleus and the response of sound - sensitive neuron to sound stimuli could be adjusted to an optimum state for signal intensity coding
根据这些变化可以推测，这种背景噪声的生物学作用可能是通过弱噪声所引起的耳蜗随机共振的输入，在上行过程中经各级听觉核团的整合，将中枢声敏感神经元调定在一种准备状态，并定型放电率函数和调制神经元对声馨硕士学位论文master ’ st砰iesis强的编码。 |
