At the optic chiasm choice point, contralateral retinal ganglion cells (RGCs) cross the midline while ipsilateral RGCs are repelled away from the midline by guidance cues. We showed that Sonic Hedgehog (Shh) is produced by contralateral RGCs at the retina, transported anterogradely along the axon, and accumulates at the optic chiasm to repel ipsilateral RGCs. These findings reveal a role for axon-axon interactions in ipsilateral RGC guidance. Our work on the genetic dissection of the role of ipsilateral RGCs in visual depth perception will also be presented.
