Neuroimaging studies using functional magnetic resonance imaging (fMRI) have provided unparalleled insights into the fundamental neural mechanisms underlying human cognitive processing, such as high-level linguistic processes during reading. Here, we build upon this prior work to capture sentence reading comprehension outside the MRI scanner using functional near infra-red spectroscopy (fNIRS) in a large sample of participants (n = 82). We observed increased task-related hemodynamic responses in prefrontal and temporal cortical regions during sentence-level reading relative to the control condition (a list of non-words), replicating prior fMRI work on cortical recruitment associated with high-level linguistic processing during reading comprehension. These results lay the groundwork towards developing adaptive systems to support novice readers and language learners by targeting the underlying cognitive processes. This work also contributes to bridging the gap between laboratory findings and more real-world applications in the realm of cognitive neuroscience.
使用功能磁共振成像 (fMRI) 的神经影像学研究为人类认知处理的基本神经机制提供了无与伦比的见解，例如阅读过程中的高级语言处理。在这里，我们在前人的工作基础上，使用功能近红外光谱 (fNIRS) 在大量参与者（n=82）中在 MRI 扫描仪外捕获句子阅读理解。我们观察到在句子级阅读期间前额叶和颞叶皮质区域的与任务相关的血液动力学反应增加，与阅读理解过程中与高级语言处理相关的 fMRI 工作中观察到的皮质募集情况相吻合。这些结果为通过针对潜在认知过程来开发支持新手读者和语言学习者的自适应系统奠定了基础。这项工作还有助于弥合认知神经科学领域实验室发现与更真实世界应用之间的差距。
