Outline of Final Research Achievements

Near-infrared spectroscopy (NIRS) is one of the noninvasive functional neuroimaging techniques. Recent studies suggested that NIRS signal is contaminated by scalp blood flow artifact. The present study propose a new method that uses only a few short-distance NIRS-channels to record and to reduce the scalp blood flow. In the proposed method, the scalp blood flow signal is estimated from the short-distance channels using principal component analysis. The estimated temporal pattern of the scalp blood flow, hemodynamic response function, temporal and dispersion derivatives, and constant were included in the design matrix for general linear model.
