Figure 1 Schematic diagram of fNIRS imagingPanel A illustrates the wavelength dependent absorption of hemoglobin and oxygen and hemoglobin, highlighting the utility of the NIR window in reducing tissue attenuation. Panel B depicts a cross-sectional view of the human head, showing light propagation through the anatomical layers and detector placement. This equation formalizes the relationship between changes in optical density and hemoglobin dynamics.
