[Responses of neurons in the cochlear nuclei of sharp-eared bats to presentation of frequency-modulated stimuli with a unidirectional change in frequency].

The investigation of the reactions of the neurons of the cochlear nuclei in the bats Myotis oxygnathus to frequency-modulated stimuli showed that the neurons with one best frequency (20%) have phasic responses while those with one or two best frequencies--tonic responses in the case when frequency of the stimulus changes from high to low frequencies.
