<prompt> Yakha inguqulo eyinkimbinkimbi yalesi sigwebo I-nucleus ebomvu ithola okokufaka okuningi okuvela ku-contralateral cerebellum nokokufaka okuvela ku-ipsilateral motor cortex.  <response>: Yiqiniso, inguqulo eyinkimbinkimbi yomusho ithi I-nucleus ebomvu ithola okokufaka okuningi okuvela ku-contralateral cerebellum nokokufaka okuvela ku-ipsilateral motor cortex, futhi ithumela ama-axon efferent ukuphonswa kwe-rubrospinal engxenyeni ephikisanayo yokwakheka kwe-rhombencephalic reticular kanye nomgogodla.
