The pontine nuclei (or griseum pontis) are the nuclei of the pons involved in motor activity. The pontine nuclei are located in the ventral pons. Corticopontine fibres carry information from the primary motor cortex to the ipsilateral pontine nucleus in the ventral pons, and the pontocerebellar projection then carries that information to the contralateral cerebellum via the middle cerebellar peduncle. Extension of these nuclei in the medulla oblongata are named arcuate nucleus (medulla) which has the same function.

| - النوى الجسرية (بالإنجليزية: Pontine nuclei) هي جزء من الجسر وتشترك في النشاط الحركي . تحمل الألياف الجسرية القشرية المعلومات من القشرة الحركية الأساسية للنواة الجسرية المقابلة في الجسر الباطني. ومن ثم يحمل البروز المخيخي الجسري تلك المعلومات إلى المخيخ المضاد عبر السويقة المخيخية الوسطى . امتداد هذه الأنوية في النخاع المستطيل يسمى بالنواة المقوسة والتي لديها نفس الوظيفة. ولذلك فهي تسمح بتعديل الحركات على ضوء نتائجها، أو تصحيح الأخطاء وبالتالي فهي مهمة في تعلم المهارات الحركية.

- Os núcleos da ponte (também chamados de núcleos pontinos ou griseum pontis) são núcleos neuronais da região encefálica da ponte envolvidos na atividade motora. Os núcleos pontinos estão localizados na ponte ventral. As fibras corticopontinas carregam informações do córtex motor primário para o núcleo pontino ipsilateral na ponte ventral, e a projeção pontocerebelar então carrega essas informações para o cerebelo contralateral por meio do pedúnculo cerebelar médio. A extensão desses núcleos na medula oblonga são denominados núcleos arqueados da medula que têm a mesma função. (pt)

They therefore allow modification of actions in the light of their outcome, or error correction, and are hence important in learning motor skills. (en)
