caption_attribution_description: This is a section in the transverse plane through the human midbrain at the level of the superior colliculus. The front of the head is near the bottom of the picture.
context_page_description: The central tegmental tract is a structure in the midbrain and pons.
  The central tegmental tract includes ascending axonal fibers that arise from the rostral nucleus solitarius and terminate in the ventral posteromedial nucleus of thalamus. Information from the thalamus will go to cortical taste area, namely the insula and frontal operculum.
  It also contains descending axonal fibers from the parvocellular red nucleus. The descending axons will project to the inferior olivary nucleus. This latter pathway will be used to connect the contralateral cerebellum.
  Lesion of the tract can cause palatal myoclonus, e.g. in myoclonic syndrome, in strokes of the Posterior Inferior Cerebellar Artery.

  The central tegmental tract includes ascending axonal fibers that arise from the rostral nucleus solitarius and terminate in the ventral posteromedial nucleus (VPM) of thalamus.  Information from the thalamus will go to cortical taste area, namely the insula and frontal operculum.
  It also contains descending axonal fibers from the parvocellular red nucleus.  The descending axons will project to the inferior olivary nucleus.  This latter pathway (the rubro-olivary tract) will be used to connect the contralateral cerebellum.
  Lesion of the tract can cause palatal myoclonus, e.g. in myoclonic syndrome, in strokes of the Posterior Inferior Cerebellar Artery.
