In the present paper, first, we describe the measurement of brain activation response during rotating a handle of a lathe by near-infrared spectroscopy (NIRS). In the frontal lobes oxy-Hb tended to increase during rotating a handle of a lathe at specified number of rotations. Second, we describe the measurement of brain activation response during lathe operation in a VR lathe environment and an actual lathe environment by NIRS. The results show that the brain activation response in the VR lathe environment was very similar to that which occurs during lathe operation in the actual lathe environment.
