Evoked potentials to gustatory stimulations in cases with unilateral facial nerve palsy

Evoked potentials to taste stimulations were discussed. New our technique of objective measurement of gustatory function by an evoked potential technique will be introduced. As a result, introduction of taste solution on the tongue innervated by facial nerve in normal subjects resulted in positive responses. Absence of taste solution did not resulted in the positive response. In case with unilateral; facial nerve palsy, introduction of taste solution on the affected side did not resulted in the positive responses.
