Abstract
I started jogging when I was 46 years old. Since then, I might become to be addicted to the running and I started investigation about running and brain. By using functional Near-Infrared Spectroscope (fNIRS), we first measured changes of the frontal lobe activity. Although walking at a speed of 1km/h activated the lower limb motor area bilaterally, running at 9km/h activated the dorsolateral prefrontal cortex. We also demonstrated that two months running training may improve frontopolar activities. This result is impressive, because this part of the prefrontal cortex is only present in the human. In order to tell those brain functions related to running, I wrote book about “Running and the Brain”.
