摘要:

目的 采用功能性近红外光谱技术(fNIRS)研究吞咽不同时期大脑皮质激活情况。

方法 2023年10月至12月,招募健康成年人18例,在fNIRS采集过程中执行视觉刺激、咀嚼、舌尖滑动和反复吞咽4项任务,计算覆盖额叶、顶叶和枕叶3个区域共计41个通道的皮质激活β值。

结果 在口腔前期,双侧运动前区和辅助运动皮质区(PSMC)、双侧额下回、右侧视觉联合皮质(AVC)和左侧初级运动皮质(PMC)被激活(P < 0.05)。在口腔准备期,右侧额下回三角部(PTG)、右侧额极区(FPA)、右侧背外侧前额叶(DPC)、左侧初级躯体感觉皮质(PSC)、左侧PSMC、左侧PMC被激活(P < 0.05)。在口腔期和咽期的过渡期,双侧PSMC,双侧PMC被激活(P < 0.05)。在口腔期和咽期两个连续时期,双侧PSC、双侧PTG、双侧FPA、双侧眶额区、双侧PSMC、双侧DPC、双侧PMC被激活(P < 0.05)。

结论吞咽运动需要额叶、顶叶和枕叶的大脑皮质共同协调完成,不同吞咽时期主要激活的脑区具有差异性,PSMC和PMC参与大部分吞咽时期。

Abstract:

Objective To explore the cerebral cortex activation in different swallowing periods using functional near-infrared spectroscopy (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 cortical 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 prefrontal gyrus, right visual association cortex (AVC), and left primary motor cortex (PMC) were significantly activated (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 significantly activated (P < 0.05). During the transition between oral and pharyngeal phases, bilateral PSMC and bilateral PMC were significantly activated (P < 0.05). Bilateral PSC, bilateral PTG, bilateral FPA, bilateral orbitofrontal area, bilateral PSMC, bilateral DPC and bilateral PMC were significantly activated during two consecutive 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.
