我们的研究结果表明，位于第十二核尾侧部的舌下神经元调节它们的放电与沿着前肢神经传递的体感信息有关。电刺激双侧桡总神经时记录单个舌下神经单位的大诱发电位和反应。脊髓舌下神经通路以前没有被描述过，但我们的研究结果表明了这种可能性。舌下神经对体感刺激的反应的延迟表明，躯体传入齐射可能会停止在网状水平，并通过脊髓网状舌下神经通路接触第十二核。先前的工作表明，视觉和前庭输入接触舌下神经核的相同尾侧区域。因此，舌头的姿势安排可能会受到前庭、视觉和体感系统的复杂控制。
Our results showed that hypoglossal neurons localized in the mediocaudal part of the XIIth nucleus modulate their firing in relation to somatosensory information travelling along the forelimb nerves. Large evoked potentials and responses of single hypoglossal units were recorded during electrical stimulation of the common radial nerve of both sides. A spinohypoglossal pathway has not been described before, but our results indicate this possibility. The latencies of the hypoglossal responses to somatosensory stimulation suggest that somatic afferent volleys may stop at the reticular level and contact the XIIth nucleus through a spinoreticulohypoglossal pathway. Previous work showed that visual and vestibular input contact the same mediocaudal region of the hypoglossal nucleus. Thus it is possible that the postural arrangement of the tongue is subject to a complex control depending on the vestibular, visual, and somatosensory system.
