The single unit activity of cochlear nuclei in Verspertilionidae are studied by means of ultrasonic pure tonal and frequency-modulated stimuli. Most neurons (85%) had tonic reaction to combination tones f2-f1 and 2f1-f2 (f1, pulse frequency of the first tone, f2 pulse frequency of the second tone) as a result of the nonlinearity in the auditory system. The reaction to the combination tones depended upon pulse frequency and sound pressure level of each of the presented stimuli. Tonic reaction appeared in the case when the combination tone was equal to the best frequency of the neuron. The question about the role of the nonlinearity of the auditory system in the resolution of the complex signals is discussed.
通过超声纯音和调频刺激研究了蝙蝠科耳蜗核的单单位活动。由于听觉系统的非线性，大多数神经元（85%）对组合音f2 - f1和2f1 - f2（f1为第一个音的脉冲频率，f2为第二个音的脉冲频率）有紧张性反应。对组合音的反应取决于每个呈现刺激的脉冲频率和声压级。当组合音等于神经元的最佳频率时出现紧张性反应。讨论了听觉系统非线性在复杂信号分辨中的作用问题。
