PA imaging results. (A) In vivo relative I ₍₅₇₀₎ (i.e., HbT; upper panel) and I_F(560) (i.e., SO₂; lower panel) PA B-scan images of selected position at different times of temperature modulation protocol. Note that the I ₍₅₇₀₎ and I_F(560) are specifically sensitive to relative HbT and SO₂ changes, respectively. The red scale bar is equivalent to 100 μm and applies to all images in panel A. Mean functional (B) HbT (i.e., R _HbT ) and (C) SO₂ (i.e., $R_{S{O}_2}$) changes resulting from in vivo temperature modulation of the rat sciatic nerve as a function of time. The error bars indicate standard deviation (n = 10).
