azimuthal angle meaning in English

方位角

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。
