In the article "Vibrissa Resonance as a Transduction Mechanism for Tactile Encoding," by Maria A. Neimark, Mark L. Andermann, John J. Hopfield, and Christopher I. Moore, which appeared on pages 6499-6509 of the July 23, 2003 issue, a printer's error removed a statement indicating that the first two authors contributed equally to the study. In addition, "vibrissa" was erroneously changed to "vibrisse" in two instances in the third paragraph of the Introduction, on the first and seventh lines of that paragraph.
