fNIRS measurement channels and task setting. Supplementary motor area: channels 13, 21, 22, and 30. Premotor cortex: channels 11, 12, 20, 28, and 29 (right) and 14, 15, 23, 31, and 32 (left). Dorsolateral prefrontal cortex: channels 18, 26, 27, and 35 (right) and 25, 33, 34, and 42 (left). Cz: T3. Protocol Rest 10 s-task 20 s-rest 10 s, 3 set × 4 tasks. The subject was given 4 random tasks and a sufficient break between the tasks.
