Figure 3From: Kalman estimator- and general linear model-based on-line brain activation mapping by near-infrared spectroscopy Representative plots of different quantities estimated on-line. Panels (a) and (b) show the NIRS time series measured from the representative channels. Panels (c) and (d) show separately the estimated critical model coefficient β 1 . Panels (e) and (f) show separately the calculated t-statistics.Back to article page
