VESTIBULAR PATHWAY

(3 - neuron crossed pathway)

  1. neuron: bipolar cells in the ganglion vestibulare - n. vestibularis - n.. VIII (some fibres form tractus vestibulocerebellaris directus pasnig without any interpolation to the cerebellum)
  2. neuron: cells in the nuclei vestibulares pontis, their axons radiate to various structures (interpolated fibres as the tractus vestibullaris indirectus to the cerebellum, tractus vestibulospinalis to the medulla spinalis, tractus vestibulonucleares to the nuclei of cranila nerves, fasciculus longitudinalis medialis, and tracts to the reticoular formation and thalamus)
  3. neuron: cells in the nuclei ventrales thalami - to brain cortex (lobus temporalis, area 41,42 - gyrus temporalis transversus /Heschl/, lobus parietalis - area 3, gyrus postcentralis)
