[Observation of facial nerve evoked potentials in rabbits].
OBJECTIVE
To investigate the possibility of recording the Antidromic Nerve Evoked Potentials (ANEP) from rabbit's scalp.


METHODS
With electrical stimulation of peripheral segment of facial nerve outside the stylomastoid foramen in rabbits, recordings were made on scalp using low-impedance silver disc electrode.


RESULTS
At the vertex, clear ANEPs composed of two waves, wave P1 and P0, were recorded in all experimental animals.


CONCLUSIONS
The study shows that ANEPs can be recorded on rabbits' scalp. The ANEPs have two waves, P1 and P0. The sources of the responses are from facial nerve and its muscle respectively.
