Popis:	We investigated the responses of single neurons in the dorsal medullar nucleus of the grass frog (Rana temporaria L.) to tones with amplitude modulated by repetitive segments of low-frequency noise. The carrier frequency corresponded to the neuronal characteristic frequency within the range of 0.2-2.0 kHz. The responses were compared with current instantaneous values of the signal amplitude and the rate of its change. We detected neurons with responses modulated either by the current signal amplitude, or the rate of change in the amplitude, or a combination of both parameters. In the vast majority of neurons, the rate of change in the amplitude played a crucial role in spike generation. The data obtained were compared with functional features of neurons located in the mammalian cochlear nucleus.
