Summary
The distribution of FMRFamide-like immunoreactivity was investigated in the brain of a myxinoid, the Pacific hagfish,Eptatretus stouti, by means of immunocytochemistry. In the forebrain, labelled cell bodies occurred in the infundibular nucleus of the hypothalamus and some closely adjacent nuclei. Labelled fibers formed a diffuse network in the forebrain, but there was no evidence for the presence of intracerebral ganglionic cells of the terminal nerve or a central projection of the terminal nerve. In the hindbrain, a group of labelled cells was found in the trigeminal sensory nucleus. A distinet terminal arborization occurred in the ventrally adjacent nucleus A of Kusunoki and around the nuclei of the branchial motor column. These findings suggest that FMRFamide may play a role in the central control of branchiomotor activity.
