不同吞咽时期大脑皮质激活特征:基于功能性近红外光谱技术
Characteristics of cerebral cortex activation in different swallowing periods based on near-infrared spectroscopy
摘要
Abstract
Objective To explore the cerebral cortex activation in different swallowing periods using functional near-infrared spec-troscopy(fNIRS). Methods From October to December 2023,a total of 18 healthy adults were recruited to perform four tasks of visual stimulation,chewing,tongue tip sliding and repeated swallowing during fNIRS acquisition,to calculate the corti-cal activation β values covering a total of 41 channels in frontal,parietal and occipital lobes. Results During the preoral period,the bilateral pre-motor and supplementary motor cortex(PSMC),bilateral inferior pre-frontal gyrus,right visual association cortex(AVC),and left primary motor cortex(PMC)were significantly acti-vated(P<0.05).During oral preparation,the right pars triangularis(PTG),right frontal polar area(FPA),right dorsolateral prefrontal cortex(DPC),left primary somatosensory cortex(PSC),left PSMC and left PMC were sig-nificantly activated(P<0.05).During the transition between oral and pharyngeal phases,bilateral PSMC and bi-lateral PMC were significantly activated(P<0.05).Bilateral PSC,bilateral PTG,bilateral FPA,bilateral orbito-frontal area,bilateral PSMC,bilateral DPC and bilateral PMC were significantly activated during two consecu-tive periods of oral and pharyngeal phases(P<0.05). Conclusion The swallowing movement requires the coordination of the frontal,parietal and occipital cortex.The main activated brain areas are different in different swallowing stages,and the PSMC and PMC are involved in most swallowing stages.关键词
