Figure 6:

Targeted tractography for seeds defined in the forebrain and midbrain of the zebrafish brain. Seed ROIs and fiber tracks are labeled with different colors including: (a-e) red/pink for the medial and lateral olfactory tracts, blue/green for the dorsal and ventral anterior commissure; (f, g) pastel green/pink for the oculomotor nerves and purple for the crossed tecto-bulbar tract. Fiber tracking illustrates nicely the connections that the olfactory tracts make between the olfactory bulbs and the ventral telencephalon with a few connections projecting into the diencephalon.
