Growth cones utilize both widespread and local directional cues in the zebrafish brain.

Abstract excerpt

The distribution of cues that provide directional information for specific growth cones in the zebrafish brain was functionally assayed by transplanting epiphysial neurons to ectopic locations in the embryonic brain followed by determining the pathways taken by the donor axons. Epiphysial axons normally first extend ventrally from their position in the dorsal diencephalon and then turn and extend anteriorly in...
