[Reactions of neurons of the acoustic area of the cerebellar vermis in cats to binaural presentation of tone signals].

In anesthetized and immobilized cats, interaural time differences at dichotic stimulation with pure tone were characteristic for maximal activity of each neuron of the cerebellar vermis lobuli VI and VII. The responses of neurons to interaural time differences were the best both at more than 10 dB above the threshold intensity and up to 2.0--2.5 kHz frequency. The maximal change of activity in specific range of time delays when fo above 4 kHz occurred irrespective of the spectrum of tone signal. Two types of neurons were revealed: responding 1) at time delays different from 0, and 2) when time delay was 0. This suggests that each of these types of neurons may play a different part in organization of elements of the localizing behaviour.
