[Research of experimental fistula stimuli vestibule evoked response].

OBJECTIVE

To investiqate a way of stimulation for experimental vestibul evoked response. The artificial fistula of right upper semicircular canal was made in 12 guineapig.

METHOD: Using a fistula stimuli probe device designed specially.

RESULT: We obtain a potential consisting of 3-4 positive waveforms. We called it the fistula stimuli vestibule evoked response (FsVeR). They had a coincide character. The response disappeared when the animal died. The cervical spinal section, orbital removal and facial nerve removal had little effects to FsVeR. When severe inner ear damage produced by Gentamycin injection, the potential disappeared. The potential disappeared but ABR were existed. When the upper semicircular canal and its nerve damage. The noise screen had a little affection to FsVeR.

CONCLUSION

These results indicated that FsVeR was mainly originated from the vestivbule system. The development of this recording technique provides a new method and maybe has important value for vestibule experimental research work.
