Systematic genetic screens have been powerful tools in identifying genes responsible for axon guidance in fruitflies and nematodes. This approach has now been extended to the study of axon guidance and the formation of topographic neuronal connections in the vertebrate brain. A systematic genetic screen was used to identify genes responsible for precise axon pathfinding and targeting in the retinotectal system of the zebrafish (Danio rerio). Over 30 genes were found that affect either: (1) retinal axon pathfinding to the contralateral tectal lobe; or (2) the topographic connection between the eye and the tectum. The zebrafish retinotectal mutants represent a new resource for the study of axon guidance in the vertebrate brain.
