Rats with geniculate laminae that run perpendicular to the lines of projection are described. Earlier reports of laminae parallel to the lines of projection were based on mammalian mutants that may be relatively common. In these mutants, the chiasmatic course of axons arising in a patch of retinal ganglion cells is wrongly specified.
