Erratum

In the article “Requirement of Nicotinic Acetylcholine Receptor Subunit β2 in the Maintenance of Spiral Ganglion Neurons during Aging,” by Jianxin Bao, Debin Lei, Yafei Du, Kevin K. Ohlemiller, Arthur L. Beaudet, and Lorna W. Role, which appeared on pages 3041-3045 of the March 23, 2005 issue, one of the National Institutes of Health (NIH) grant numbers listed (NS29071) is incorrect. Support for L. W. Role was actually provided by NIH Grant NS22061.
