本研究利用功能性近红外光谱研究了背外侧前额叶皮层（DLPFC）和左腹外侧前额叶皮层（VLPFC）的工作记忆能力与大脑活动之间的关系。我们进行了阅读广度测试语言任务来测量语言工作记忆，同时我们评估了任务期间脑血流量变化所反映的大脑活动。 DLPFC脑血流量变化与阅读广度测试得分呈负相关。在高分组和低分组的任务期间的前半部分和后半部分中，两个聚焦区域都表现出不同的脑血流变化模式。我们的研究结果表明，大脑活动与阅读广度测试分数相关，而阅读广度测试分数又与语言工作记忆能力相关。因此，利用功能性近红外光谱仪测量 DLPFC 中的大脑活动可用于间接评估工作记忆能力。
The present study investigated the relationship between working memory capacity and brain activity in the dorsolateral prefrontal cortex (DLPFC) and the left ventrolateral prefrontal cortex (VLPFC) using functional near-infrared spectroscopy. We administered the reading span test language task to measure linguistic working memory, while we assessed brain activity reflected in the cerebral blood flow change during the task. The cerebral blood flow change in the DLPFC had a negative correlation with the reading span test score. Both focused regions exhibited different patterns of cerebral blood flow changes during the first and second halves of the task period in the high- and low-score groups. Our findings suggest that the brain activity correlates with the reading span test score, which is associated with linguistic working memory capacity. Therefore, brain activity measurement in the DLPFC with the functional near-infrared spectroscopy can be used to indirectly assess working memory capacity.
