声源方位 meaning in Chinese
sound bearing
sound emanate direction
Examples
- In contrast , although application of bicuculline essentially had no effect on the bfs of ic neurons , it differentially broadened neurons ftcs at different azimuths abolishing the direction - dependent sharpening of frequency tuning
本研究还提示，听皮层对下丘神经元频率调谐的方向敏感性的调制，可能是通过改变神经元在不同声源方位的抑制区的大小实现的。 - 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
当声源方位由记录部位对侧移向同侧时，大多数神经元接受的gaba能抑制性输入的量增加，与兴奋性输入整合后，导致了频率调谐特性的方向性差异。 - 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
结果表明，声源方位对下丘听神经元频率调谐曲线的锐度、最低阈值有影响，多数神经元在记录部位同侧的频率调谐曲线的锐度比对侧大，最低阈值比对侧高。 - This study showed that the mt and sharpness of frequency tuning curves increased as the sound direction changed from contralateral to ipsilateral azimuthal angles . it suggests that sound direction effect on frequency tuning may be through the complex interplay between the excitatory and inhibitory inputs . the application of gaba ( a ) antagonist , bicuculline , lowered all mts but the application did not abolish direction - dependent variation in mt
听皮层的抑制性影响使大多数神经元在蝙蝠最敏感的声源方位c - 40的频率分辨能力明显提高，同时使c - 40和i - 40的最低阈值的差别进一步增大，提高了信噪比，提高下丘听神经元对声源方位和最佳频率的分辨能力。
