Activation of the Prefrontal Cortex While Performing a Task at Preferred Slow Pace and Metronome Slow Pace: A Functional Near-Infrared Spectroscopy Study

Localization of regions of interest. The numbers on small spheres on the brain map indicate the 42 channels. The channel localization was based on lower central probe, which was anchored at Fpz according to international 10–20 system and was located at the midpoint between channels numbers 38 and 39. The red channels (numbers 21, 22, and 30) were located in the FPPFC (BA 10), the blue channels (numbers 2, 3, 4, and 10 on the right and numbers 5, 6, 7, and 16 on the left) were located in the DLPFC (BA 9 and 46), and the green channels (numbers 18, 27, 35, and 36 on the right and numbers 25, 33, 41, and 42 on the left) were located in the VLPFC (BA 44, 45, and 47).
