Brain Activities Supporting Finger Operations, Analyzed by Neuro-NIRS

Brain activities are analyzed for the button selection task using Neuro-NIRS, which is analysis method of quick component of NIRS. Quick component of NIRS is numerically quantifies by short time average of absolute value. The average is represented by, maximum and density. Since button selection task is short time event, it seems the instantaneous activities, like maximum is playing major roles in finger selection to operate button.
