Projection pathways in the margin of auditory nuclei in the songbird mesencephal on 鳴禽中腦聽覺核團(tuán)邊緣區(qū)神經(jīng)投射的研究
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 根據(jù)這些變化可以推測(cè),這種背景噪聲的生物學(xué)作用可能是通過(guò)弱噪聲所引起的耳蝸隨機(jī)共振的輸入,在上行過(guò)程中經(jīng)各級(jí)聽覺核團(tuán)的整合,將中樞聲敏感神經(jīng)元調(diào)定在一種準(zhǔn)備狀態(tài),并定型放電率函數(shù)和調(diào)制神經(jīng)元對(duì)聲馨碩士學(xué)位論文master’st砰iesis強(qiáng)的編碼。
