(a) Optical spectra from the broadband bNIRS study in Ref. 38 before, during, and after inducing HI in the piglet’s brain. (b) Predictions of the molecular concentration change $\{\delta c_{{\mathrm{HbO}}_2},\delta c_{\mathrm{HHb}},\delta c_{\mathrm{diffCCO}}\}$ over the course of the optical monitoring (for the Beer–Lambert model without scattering). The vertical lines denote the time points corresponding to the normalized reflection spectra on the left.
