功能性近红外光谱（fNIRS）是一种非侵入性的光学神经成像技术，在研究和临床应用中已显示出其在监测脑活动方面的巨大潜力，可替代功能性磁共振成像（fMRI）。fNIRS在研究健康受试者和人工耳蜗使用者的听觉皮层中的应用越来越多。然而，fNIRS易受运动伪影的影响，尤其是与下颌运动相关的伪影，这会影响语音和听觉任务中的fNIRS信号。本研究旨在研究人类受试者中与下颌运动相关的运动伪影，包括紧咬，说话，吞咽和嗅闻，并测试我们先前建立的去噪算法PCA-GLM是否可以减少运动伪影。我们的研究结果表明，下颌运动引入了类似于任务诱发激活的伪影，并且PCA-GLM方法有效地减少了由于咬紧运动引起的运动伪影。本研究的初步结果强调了去除fNIRS信号中与下颌运动相关的伪影的重要性，并表明我们的PCA-GLM方法在减少运动伪影方面的有效性。临床相关性-这项工作研究了在语音感知和生产任务中经常发生的下颌运动引起的运动伪影，并验证了已建立的去噪算法的有效性，该算法有利于fNIRS研究听觉和语言功能。
Functional near-infrared spectroscopy (fNIRS), a non-invasive optical neuroimaging technique, has demonstrated its great potential in monitoring cerebral activity as an alternative to functional magnetic resonance imaging (fMRI) in research and clinical usage. fNIRS has seen increasing applications in studying the auditory cortex in healthy subjects and cochlear implant users. However, fNIRS is susceptible to motion artifacts, especially those related to jaw movement, which can affect fNIRS signals in speech and auditory tasks. This study aimed to investigate the motion artifacts related to jaw movements including clenching, speaking, swallowing, and sniffing in a group of human subjects, and test whether our previously established denoising algorithm namely PCA-GLM can reduce the motion artifacts. Our results have shown that the jaw movements introduced artifacts that resemble task-evoked activations and that the PCA-GLM method effectively reduced the motion artifacts due to the clenching movements. The preliminary results of the present study underline the importance of the removal of the jaw-movement-related artifacts in fNIRS signals and suggest the efficacy of our PCA-GLM method in reducing the motion artifacts. Clinical Relevance— This work studies the motion artifacts due to jaw movements that frequently occur in speech perception and production tasks and validates the efficacy of an established denoising algorithm which benefits fNIRS studies on auditory and language functions.
