central tegmental tract

The central tegmental tract, a structure in the midbrain and pons.

Palatal myoclonus may be observed due to disruption of the central tegmental tract.

Chronic clonus is often due to lesions of the central tegmental tract (which connects the red nucleus to the ipsilateral inferior olivary nucleus).

Fibers of the rubro-olivary tract project from the parvocellular red nucleus via the central tegmental tract to the ipsilateral inferior olivary nucleus.

Palatal myoclonus may be seen as a component of the lateral medullary syndrome (a.k.a. Wallenberg Syndrome), if the infarction extends to involve the central tegmental tract.

Ascending secondary neurons originating in nucleus solitarius project bilaterally to the ventral posteromedial (VPM) nuclei of the thalamus via the central tegmental tract.

Central tegmental tract: Directly anterior to the floor of the 4th ventricle, this is a pathway by which many tracts project up to the cortex and down to the spinal cord.

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.

The descending rubrospinal tract and reticulospinal tract originate in the red nucleus and reticular formation (which is closely associated with the central tegmental tract) respectively, thereby providing the mechanism by which this circuit exerts its effects on spinal cord motor activity.
