Retrograde and transganglionic transport of horseradish peroxidase has been used to study the cell bodies of origin and the central projections of neurons innervating the rat masseter muscle. Labeled cell bodies were observed both in the trigeminal ganglion and in the mesencephalic trigeminal nucleus. Major central projections from mesencephalic trigeminal(More)
The effects of peripheral nerve transection on mesencephalic trigeminal (MeV) neurons have been studied qualitatively and quantitatively in the rat. In the qualitative part of the study the brain stem was studied in Fink-Heimer stained sections 3-30 days after a masseteric nerve transection. Degeneration argyrophilia was observed both in the MeV tract and(More)
Retrograde and transganglionic transport of horseradish peroxidase conjugated to the B-fragment of cholera toxin (B-HRP) was used to study the location, morphology, and central projections of mesencephalic trigeminal (Me5) neurons innervating rat masticatory muscles. Labeled Me5 cell bodies were found throughout the Me5 nucleus from a level slightly caudal(More)
Certain populations of dorsal root ganglion cells upregulate galanin (GAL) and neuropeptide Y (NPY) after peripheral axotomy. Less is known of the functional properties of the neurones reacting in this way. The primary sensory mesencephalic trigeminal (Me5) neurones are considered to have purely proprioceptive functions. In this study immunohistochemistry(More)
