The pontine nuclei (or griseum pontis) are the

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.

They therefore allow modification of actions in the light of their outcome, or error correction, and are hence important in learning

motor skills
.

It is also responsible of the activation of ¨REM on¨ neurons. Depending on exact size and location, bilateral lesions in this structure can completely block REM sleep or REM sleep components
