Variability in tissue oxygenation despite qualitatively consistent blood flow. a) Blood flow (top) and tissue reflectance (bottom) maps prior to SD with superimposed ROIs for temporal traces. Arrows and dashed white circles indicate SD propagation direction. b) Temporal traces of i) blood flow and ii) tissue oxygenation for the two ROIs proximal to the paired iii) LFP and iv) KSE tips with their corresponding traces. c) Temporal traces of blood flow versus tissue oxygenation for ROIs across the FOV labeled i-vi in reflectance map.
