title: Effects of vestibular nerve section on sound-evoked myogenic potentials in the sternocleidomastoid muscle of monkeys.
abstract: OBJECTIVE
  The aim of this study was to elucidate the neural pathway for sound-evoked myogenic potentials (SEMPs) in monkeys with characteristics similar to those of vestibular evoked myogenic potentials in humans.
  
  
  METHODS
  Six macaque monkeys were examined. The effects of total and selective vestibular nerve section on the SEMPs were evaluated in three monkeys.
  
  
  RESULTS
  After total vestibular nerve section, the SEMPs and caloric nystagmus were eliminated, and the auditory brainstem response remained. After selective superior vestibular nerve section, the SEMPs remained, but caloric nystagmus was eliminated.
  
  
  CONCLUSIONS
  The inferior vestibular nerve comprises a neural pathway for SEMPs in monkeys.
  
  
  CONCLUSIONS
  SEMP in monkeys may provide a model of human VEMPs.
