Fig. 2. (Color online) Combined SHG and TPEF images of the mouse cerebellum and brain stem slices. (a) SHG image shown in hot colormap, (b) TPEF image in green, (c) the merged SHG/TPEF image of the cerebellar cortex. The black, blue, and white arrows indicate the neuron somas in ML, PCL, and GL, respectively. (d)–(f) are the SHG image (hot colormap), TPEF (green), and the merged images SHG/TPEF of icp and SP5. Scale bars in (c) and (f) are 100 μm.
