Pontine nuclei
（重定向自Nuclei pontis）
The pontine nuclei (or griseum pontis) are a part of the pons involved in motor activity. 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.
