使用 Flanker 任务进行并发脑电图和功能近红外光谱记录

Overview

This study presents a protocol for conducting simultaneous EEG and fNIRS recordings to assess the neuroactivation patterns during a flanker task. By integrating these techniques, the relationship between the activity in the prefrontal cortex and various event-related potentials is examined, providing insights into cognitive processing.
