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. )
本實驗旨在探討弱噪聲對小鼠( musmusculuskm )中腦下丘( inferiorcolliculusic )神經元聲信號提取的影響及其神經機制,我們選用相當于純音閾下5db的白噪聲( whitenoise ) ,比較加入噪聲前後神經元頻率調諧曲線的變化和注射-氨基丁酸( - aminobutyricacid , gaba )能受體拮抗劑荷包牡丹堿( bicuculline , bic )后對該變化的影響。Were used for this study. durations of tone and weak white noise bursts used as sound stimuli were both 40 ms ( 2 - ms rise - decay times ), and delivered synchronally at 2 per second in free field. 177 neurons were obtained in this experiment, and frequency tuning curves ( ftcs ) of 76 ic neurons were measured in our study
本實驗共用12隻健康、聽力正常的成年小鼠,雌雄不拘,共獲得177個神經元,測量了76個神經元的頻率調諧曲線( frequencytuningcurve , ftc ) ,發現弱噪聲對神經元ftc的影響有三種類型:銳化、拓寬和基本不受影響。As a classical and practical method in ambient vibration experimental modal analysis, auto - cross spectrum density method replace the frequency response function with power spectrum and achieve its mode shape from transmissibility between the response signals and reference signal
自互譜法作為環境激勵實驗模態分析的一種實用的經典方法,用響應點和參考點間的功率譜曲線來代替頻響函數曲線,並由響應點和參考點之間響應的傳遞率得出振型。
