[Responses of neurons of the supraolivary complex to amplitude-modulated signals].
46% out of 160 studied neurons synchronized their discharges according to the envelope of sinusoidal amplitude-modulated (AM) stimuli when modulating frequency was changed from 50/sec to 1200/sec. The areas of synchronization coincided with the excitatory areas for tonal stimuli. The synchronization was found to depend on intensity of stimulus, and for some units the upper threshods were revealed. The other parameters of AM-stimulus such as the coefficient of modulation and modulating frequency, also act on the synchronization.
