Abstract

This study evaluates a low-cost, single-channel fNIRS device in cognitive neuroscience, aiming to overcome the financial barriers of commercial systems by testing its efficacy in tasks of varying complexity. Twenty-six participants engaged in motor control (finger-tapping), working memory (n-back), and creativity (AUT) tasks while their prefrontal cortex activity was monitored using the device, with behavioral and cerebral blood flow changes recorded. Results showed the device's capability to detect significant blood flow variations across different tasks, thereby supporting its use in cognitive research. The study confirms the potential of single-channel fNIRS as a cost-effective tool for diverse cognitive assessments, from simple motor actions to complex creative thinking.

摘要

本研究评估了一种用于认知神经科学的低成本单通道功能近红外光谱（fNIRS）设备，旨在通过测试其在不同复杂程度任务中的功效来克服商业系统的资金障碍。26名参与者在进行运动控制（手指敲击）、工作记忆（n-back）和创造力（AUT）任务时，使用该设备监测其前额叶皮层活动，并记录行为和脑血流变化。结果显示该设备能够检测出不同任务之间显著的血流变化，从而支持其在认知研究中的应用。该研究证实了单通道fNIRS作为一种经济高效的工具用于从简单运动行为到复杂创造性思维等多种认知评估的潜力。
