corticofugal
解釋
離皮層的-
Corticofugal modulation of frequency tuning of inferior collicular neurons in big brown bat, eptesicus fuse us chinese science bulletin, 2000 in order to explore the possible mechanism of corticofugal modulation of excitatory frequency tuning curves ( eftcs ) of midbrain neurons, we examine the change of sharpness, frequency - intensity response area, minimum threshold of both eftcs and inhibitory frequency tuning curves ( iftcs ) of inferior coliicular neurons during corticofugal modulation using two - tone inhibition paradigm and micro - electrical stimulation technique
第二章大棕幅聽皮層對中腦下丘聽神經元頻率調諧曲線的調制科學通報， 2000用雙聲刺激的方法和電刺激技術，進一步研究了在激活聽皮層前後下丘聽神經元興奮性和抑制性頻率調諧曲線的銳度、頻率強度反應區域、最低閾值的協同變化 -
During corticofugal inhibition, the percent change of frequency - intensity response area of eftcs had significant correlation with the percent change of that of iftcs. these data suggest that cortical neurons are likely to improve frequency information processing of inferior collicular neurons by modulation of iftcs
當聲源方位由記錄部位對側移向同側時，大多數神經元接受的gaba能抑制性輸入的量增加，與興奮性輸入整合后，導致了頻率調諧特性的方向性差異。 -
The opposite results were observed for excitatory and inhibitory ftcs of corticofugally facilitated icc neurons. corticofugal inhibition increased sharpness, minimum threshold, and decreased the frequency - intensity response area of eftcs, at the same time it decreased the sharpness, minimum threshold but increased the frequency - intensity response area of iftcs
結果表明，聲源方位對下丘聽神經元頻率調諧曲線的銳度、最低閾值有影響，多數神經元在記錄部位同側的頻率調諧曲線的銳度比對側大，最低閾值比對側高。 -
These data indicate that gabaergic inhibition makes an important contribution to the direction - dependent frequency tuning of most ic neurons. corticofugal modulation of the excitatory and inhibitory ftcs of most ic neurons was more pronounced at one sound direction than the other. sound direction effects on frequency tuning characteristics may undergo a postnatal development due to the development of excitation and inhibition integration
通過對幼年（出生后第四周）和成年蝙蝠下丘聽神經元頻率調諧的方向敏感性的比較，發現幼年蝙蝠頻率調諧的方向敏感性比成年蝙蝠差，並認為可能是動物發育過程中，下丘的興奮性和抑制性輸入的整合也有一個發育的過程。 -
These data support previous reports that corticofugal systems work together with widespread lateral inhibition to regulate subcortical frequency processing
該發現支持了以前關于聽覺系統中通過廣泛的抑制作用來調制聽覺信息處理的假說。 -
In terms of our results, it is hypothesized that in the central auditory system when the sound information is conducting through continuous synaptic clefts, there are interactions and integrations occurring between the ascending and corticofugal descending pathways with neural inhibition or facilitation so as to realize the neural integration that diverging or converging sound information with new forms, which ensures the neurons tune the sound information with biological significance
據此推測，當神經元的信號在不同聽中樞結構中通過連續的突觸連接時，上行性或離皮層下行性神經抑制或神經易化通路之間在不斷地發生相互作用與整合，從而使得聲信息以新的方式分散或聚合，實現新的神經整合過程，以保證神經元調諧有生物學意義的聲信號。
