Abstract
【aims】We analyzed changes in brain activity during a short period of non-dominant chopstick use learning. 【Methods】The 49 channels fNIRS measurement were assessed, and we analyzed the relative value of oxyhemoglobin in FP, DLPFC, FEF, PMC, and M1 in both hemispheres during practice. We also evaluated the motor skills before and after practice. 【Results】The motor skills of left and right hands improved after practice. Brain activity during left-hand practice showed activation of FP, DLPFC, FEF, and PMC in the left and right hemispheres, and a significant decrease in activity in FP in the left and right hemispheres, and DLPFC in the left hemisphere. 【Discussion】The results suggest that motor control using sensory information and cognitive activity were performed in the trial and error stage in the early stage of motor learning.
