Hypoglossal high threshold afferents projecting to the secondary somatosensory area in the cat.
Recording with microelectrodes in the anterior ectosylvian area of the cerebral cortex in cats showed responses on stimulation of the hypoglossal nerve. The responses persisted after cutting the hypoglossal rootlets close to the brainstem but disappeared after cutting the glossopharyngeal and vagal roots. The responses were high threshold and probably mediated by "pain fibers".
