Normal LGN refinement in <i>Dscam^3J</i> mutant.

<p>Cholera toxin labeled with alexa-488 or cy3 was injected into the right (cy3) or left (488) eyes of wild type and <i>Dscam^3J</i> mutant mice to assay refinement of axonal projections. Both ipsilateral and contralateral projections of <i>Dscam^3J</i> mutant mice were similar to wild type. The scale bar in (B) is equivalent to 225 µm.
