Three guidance receptors implicated in visual system development. (A, B) Roughest resides in a punctate pattern in axons during axon pathfinding and visual map formation and becomes restricted to synaptic neuropils during synapse formation. (C, D) Fasciclin 2 resides evenly on photoreceptor axons throughout visual map formation. (E, F) N-Cadherin is enriched in areas of future and ongoing synapse formation. Guidance Receptors are labeled in green; synapses labeled for Synaptotagmin in blue.
