R2 (A) and normalized MSE (B) vs. Mayer wave amplitude (in Molars) in HbO signal. Comparison of R2 (C) and absolute MSE (D) obtained using GLM with and without short separation regression. Percentages on the lower panels show the percent of data points above or below the midline. Note that results are shown for HRF estimation after introducing a signal change of 0.2% from baseline for the 690 nm and 0.4% for 830 nm producing an evoked HbO change of of 0.14 µM in the NIRS data (case 2).
