Abstract

Experiments on anesthetized cats have shown that the frequency following response (FFR) which is typical of the lower regions of the auditory system (including the inferior colliculus) may reflect all basic properties of the auditory stimuli. The amplitude and the wave-form of the FFR depend greatly on frequency and intensity of the stimuli, their wave-form and periodicity, masking by noise, as well as interaural differences in stimulation modelling different spatial positions of the sound source.

摘要

对麻醉猫的实验表明，听觉系统较低区域（包括下丘）特有的频率跟随反应（FFR）可能反映听觉刺激的所有基本特性。FFR的幅度和波形在很大程度上取决于刺激的频率和强度、其波形和周期性、噪声掩蔽以及模拟声源不同空间位置的刺激的双耳差异。
