Abstract:
The localization of human swallowing cortical area remains unclear,which prevents the understanding of pathophysiologic change of peripheral swallowing apparatus and the development of swallowing rehabilitation.Animal experiments have found that the non-human primates, premotor cortex,sensorimotor area,frontal,parietal and temple operculum,orbitofrontal cortex and cingulate cortex are associated with swallowing function.Recently,by using the advanced techniques such as functional MRI,position emission tomography and magnetoencephalography,it was found that a number of encephalic regions participated in the human swallowing,mostly concentrated in primary sensorimotor cortex,premotor cortex,cingule,insular lobe,and parietal-occipital area.However,the exact functions and roles of various encephalic regions and their correlations between various encephalic regions remain unclear.Further studies are needed to identify them.
