“…Anatomical studies demonstrate that afferent fibres of the extraocular muscle proprioceptors terminate particularly in the ventrolateral part of the 5i and the 5c (Porter, 1986;Porter and Donaldson, 1991). Our results indicate that the neurones of the ventral 5c reach the IVN, MVN, and LVN, whereas those in the ventral 5i also reach the SVN.…”

“…These trigeminal regions receive their sensory innervation from the ophthalmic division of the trigeminal nerve (Panneton and Burton, 1981;Marfurt and Del Toro, 1987;Ogasawara et al, 1987;Buisseret-Delmas and Buisseret, 1990;Porter and Donaldson, 1991;Van Ham and Yeo, 1996b). It is tempting to speculate that sensory information mediated by the ophthalmic branch of the trigeminal nerve may have an influence on complex behavioral mecha- nisms involved in the control of head and gaze stabilization during mastication.…”

“…Unlike other primary sensory neurons whose cell bodies are located in peripheral ganglia, Me5 contains the only primary sensory neurons located within the central nervous system (Capra and Wax, 1989;Porter and Donaldson, 1991). These cells are believed to be derived from the mesencephalic neural crest (Narayanan and Narayanan, 1978;.…”

The mesencephalic trigeminal nucleus (Me5) innervates muscle spindles and is responsible for receiving and transmitting proprioception from the oro-facial region. Molecular mechanisms underlying the development of the Me5 are poorly understood. Evidence is provided here that transcription factor Drg11 is required for Me5 development. Drg11 was expressed in the Me5 cells of the embryonic and early postnatal mouse brains, and the Me5 cells were absent in Drg11 −/− mice at birth. The absence of the Me5 cells in Drg11 −/− mice appeared to be caused by increased cell death in the Me5 during embryonic development. In postnatal Drg11 −/− mice, Me5 cell innervation of masseter muscle spindles was undetectable, while robust trigeminal motoneuron innervation of masseter muscle fibers was detected. The postnatal bodyweight of Drg11 −/− mice was notably less than that of wild-type mice, and this might result, in part, from disruption of the oro-facial proprioceptive afferent pathway. Taken together, our results demonstrate an essential role for Drg11 in the development of the Me5.
