Summary:Near-Infrared Spectroscopy (NIRS) is used to measure the concentration change of oxygenated hemoglobin (ΔHbO) and deoxygenated hemoglobin (ΔHHb) on two sides of primary motor cortex in the human brain by stimulating two hand of participant moving up and down in succession. In this research, we demonstrate the ability analyze signal of human brain activity using a 20-chanels continuous wave optical NIRS system over the primary motor cortex of 3 healthy males. We propose a method analysis based on the theory of angular coefficient in the line and calculating the mean to distinguish the data offline of left and right hand moving with an average accuracy 86.77% for all volunteers. The result indicates potential application of this method in processing signal from NIRS. We also discuss here the ability of application of our method can be used for the development of brain-computer interface (BCI) in the future.
