Effect of rock-paper-scissors exercise on cerebral blood oxygenation during a verbal memory task measured by fNIRS

Functional near-infrared spectroscopy (fNIRS) was used to study changes in cerebral blood oxygenation during a verbal memory task. Six right-handed male and four female volunteers matched on demographic variables and verbal memory performance participated in the study. Prior to verbal memory tasks, four verbal fluency tasks were loaded in order to obtain information of standard cerebral blood oxygenation for each subject. Effect of rock-paper-scissors exercise as easy finger action on cerebral blood flow was examined during the verbal memory tasks. Significant responses were observed in the left prefrontal cortex, the insula bilaterally, the midline supplementary motor area, and the medial parietal cortex.
