  • Title: A somatotopic and functional organization of the masticatory proprioceptors in the mesencephalic trigeminal nucleus of the frog.
    Author: Marini R, Bortolami R.
    Journal: Arch Ital Biol; 1982 Sep; 120(4):385-96. PubMed ID: 6983331.
    Abstract:
    A stratified organization of the first-order neurons of the masticatory proprioception has been observed in the frog mesencephalic trigeminal nucleus (MeNV). Extracellular records of unit activity have shown that in this nucleus neurons responding either to jaw raising muscles or to jaw lowering muscles reveal a somatotopy. A consistent topography pattern is evident by exploring in dorsoventral direction the layers 4 and 6 in the optic tectum. The jaw closing muscles are represented in the dorsal part of the MeNV, whereas the jaw opening ones are distributed more ventrally. Since MeNV neurons represents the afferent limb of the masticatory reflex, the motor effects elicited by electrical stimulation of these cells have been tested.
