It is reported about myography on testpersons with normal vestibular function as well as on patients after operativ dissection of the VIII. nerve, neuropathia nerv. vest. and M. Menière. On the base of these findings it is supposed that myography proofes to be a useful help in the judgement of the specific influence of the vestibular organs on the motoric system. The myographic changes of the muscular activity after caloric stimulation give exact information about the entire vestibular system and especially about the vestibular-spinal-pathways. The best way of testing the vestibular activity is performed on musculars with symmetric, simultaneous and reziproke intented innervation, f.i. on the sternocleidomastoidei muscels in slight deflected position of the head. Most significant for the vestibular influence are an increase of the base-activity and the appearance of groups of potentials which are related to the vestibular stimulus in time and intensity.
