MeSH [1]

The basis pontis is the anterior portion of the pons.

Clinical significance

Infarction in this region can impair functioning.[1]

The basis pontis undergoes demyelination in the condition known as central pontine myelinolysis. This condition is due to the rapid intravenous correction of hyponatremia.
