Simultaneous bilateral recordings of ABR in cats were performed using binaural and monaural stimulation following the section of the eighth nerve and the auditory ascending cross pathway (cochlear nucleus-superior olivary nucleus level).
The results were as follows:
1) Waves 1 and 2 seem to represent the potentials of the ipsilateral cochlear nerve and cochlear nucleus.
2) Waves 3, 4 and 5 seem to represent the potentials of the contralateral brainstem evoked potentials.
3) Wave 3 is related to the contralateral superior olivary nucleus, wave 4 to the contralateral superior olivary ascending pathway and wave 5 to the contralateral inferior colliculus.
4) In order to locate the lesions, ABR should be evaluated whether there is the response to binaural or monaural stimulation or not.
