title: Vestibular and auditory influences on segmental motoneuron excitability--a comparative study.
abstract: This study aimed to investigate the vestibular and acoustic influences on segmental motoneuron excitability in the same normals in order to compare the effects of both sensory systems. The results show that both systems exert similar influences on H-reflex in the same subjects. These indicate similarities in the function of motor control and suggest common final pathways of the vestibular and auditory activity to the segmental motoneuron. The alternative effect, facilitation or inhibition, of acoustic and vestibular stimuli on H-reflex is devoted to processing of the labyrinthine activation in the brainstem reticular formation, or to the state of the spinal interneurons.
