Figure 4From: Kalman estimator- and general linear model-based on-line brain activation mapping by near-infrared spectroscopy Representative snapshots of the activation map at different times, for different subjects. Rows (a) to (f) show t-images of the four subjects at different times (T = 120, 200, 300, 400, 500, and 552 sec). Row (f) shows t-images of four subjects estimated by the conventional GLM-based method. The results are presented by means of NFRI tools [47].Back to article page
