Vestibular-evoked myogenic potentials recorded from miniature pigs and rats

VEMP can be induced from both neck extensor and masseter muscles in the miniature pig and rat. For a given species, the site of recording affects P wave induction rate and amplitude but not latency. Consistency and repeatability analysis suggests that the masseter muscle is a better recording site in miniature pigs while the cervical extensor is a better recording site in rats. For a given recording site, both latency and amplitude of the P wave are slightly greater in miniature pigs than in rats.
