Corrected diffuse reflectance data (open circles) and fits (solid line) for detector fibers 1, 2, 4, and 5 for subject 3 (a) pre-MB $(\mathrm{SRSE}=1.18\times {10}^{15})$ and (b) post-MB $(\mathrm{SRSE}=1.13\times {10}^{15})$, and subject 8 (c) pre-MB ($\mathrm{SRSE}=1.32\times {10}^{15})$ and (d) post-MB ($\mathrm{SRSE}=1.36\times {10}^{15}$). Colors and symbols indicate different detector fibers.
