英文摘要: The ascending pathway mediating proprioception from the orofacial region is still not fully known. The present study elucidated the relay of jaw-closing muscle spindle (JCMS) inputs from brainstem to thalamus in rats. We injected an anterograde tracer into the electrophysiologically identified supratrigeminal nucleus (Su5), known to receive JCMS input. Many thalamic axon terminals were labeled and were found mainly contralaterally in a small, unpredicted area of the caudo-ventromedial edge (VPMcvm) of ventral posteromedial thalamic nucleus (VPM). Electrical stimulation of the masseter nerve and passive jaw movements induced large responses in the VPMcvm. The VPMcvm is far from the rostrodorsal part of ventral posterolateral thalamic nucleus (VPL) where proprioceptive inputs from the body...
