Qu'est-ce (qui) est nuclei pontis - définition

PARTS OF THE MAMMALIAN BRAIN
Nuclei pontis; Pontine nucleus; Griseum pontis

Pontine nuclei         
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.
Deep cerebellar nuclei         
Independent centers of gray substance; Deep cerebellar nucleus; Nuclei cerebelli
The cerebellum has four deep cerebellar nuclei embedded in the white matter in its center. 4 pairs of nuclei are embedded deep in the medullary centre, in the medial to lateral direction.
Trigeminal nerve nuclei         
Trigeminal nucleus; Nuclei of the trigeminal nerve; Nucleus of the trigeminal nerve; Trigeminal nuclei; Primary sensory trigeminal nucleus; Trigeminal nerve nucleus
The sensory trigeminal nerve nuclei are the largest of the cranial nerve nuclei, and extend through the whole of the midbrain, pons and medulla, and into the high cervical spinal cord.

Pontine nuclei

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.

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