For This Week in the Journal feature page of the June 23, 2004 issue, the page range listed for the article highlighted in the Development/Plasticity/Repair section is incorrect in the print version of the Journal. The article (by Chizhikov and Millen) actually appears on pages 5694-5702. In the article itself, “Control of Roof Plate Development and Signaling by Lmx1b in the Caudal Vertebrate CNS,” by Victor Chizhikov and Kathleen J. Millen, the DOI number given beneath the correspondence address is not correct as shown in the print version. The DOI number for this article should have been listed as “`DOI:10.1523/JNEUROSCI.0758-04.2004.”
