[2] In humans it is very small and runs ventral to the lateral corticospinal tract.

[1][3] The inferior olivary nucleus projects to the contralateral cerebellum via olivocerebellar fibers.

Ascending reticulothalamic fibres project from the medial zone nuclei of the reticular formation to the hypothalamus (to mediate autonomic nervous system response), and the intralaminar thalamic nuclei (to mediate a startle response to pain).

[3] Lesion of the tract can cause palatal myoclonus, e.g. in myoclonic syndrome, in strokes of the posterior inferior cerebellar artery.
