The role of the vagal pathway and gastric dopamine in the gastroparesis of rats after a 6‐hydroxydopamine microinjection in the substantia nigra

Abstract

Dopaminergic deficiency in the SN results in impaired gastric motility, possibly as a result of the enhanced activity of dopamine system and reduced Ach in gastric tissue. The vagus nerve plays an important role in peripheral gastric motility disorder.
