Impulse responses of single units located in the torus semicircularis of the immobilized lake frog (Rana ridibunda) to long-lasting characteristic frequency tones modulated by low-frequency pseudorandom noise were registered. Period histograms locked to the direct and inverted modulating waveform with duration of 512 ms were obtained for 32 units. The majority of the histograms revealed the rectification of the envelope waveform in the neural discharge patterns. So, the difference histograms were calculated which in some units represented the stimulus envelope waveform rather well. Other units strongly emphasized the envelope maxima in their responses. In many cases only a few maxima of the envelope were represented in the period histograms. There were neurons that retained peculiarities of their response in the wide range of the carrier intensities.
记录了固定的湖蛙（泽蛙）半规管环中的单个神经元对由低频伪随机噪声调制的持续特征频率音调的冲动反应。对32个神经元获得了锁定到持续时间为512毫秒的直接和反向调制波形的周期直方图。大多数直方图显示神经放电模式中包络波形的整流。因此，计算了差异直方图，在一些神经元中，差异直方图相当好地代表了刺激包络波形。其他神经元在其反应中强烈强调包络最大值。在许多情况下，周期直方图中仅呈现了包络的少数最大值。存在一些神经元，它们在载波强度的广泛范围内保持其反应特性。
