Fig. 4.
Attenuation-change spectra back-calculated from the calculated concentration changes at peak Δ[oxCCO] response for different subjects. The presented spectra are the average of all spectra falling within the window of peak Δ[oxCCO] activation. The difference between the 3 and the 2-chromophore fit is plotted. All data are from the furthest detector. The symbols at the top left-hand-side corner of each plot indicate the correspondence with Fig. 3, 5 and 6.
