Fig. 7.

3D structure of zebrafish’s brain. (a) to (d) are raw images from in vivo imaging showing four different sections. The scale bar is 100 μm in (a). (e) to (h) show enlarged views of four regions labeled in (a) to (d), demonstrating cellular resolution at different depths in the brain. The scale bar is 20 μm in (e). (i) is one slice from lateral view (xz) of zebrafish’s brain reconstructed by the raw images. The structure of optic tectum, epencephala and hindbrain are apparent. The scale bar is 100 μm. (j) and (k) are the enlarged views of regions labeled in (i), demonstrating the cellular resolution in the whole-brain. The scale bar is 20 μm in (j).
