In the article by Nikita Gamper, Vitaliy Reznikov, Yoichi Yamada, Jian Yang, and Mark S. Shapiro that appears on pages 10980-10992 of the December 1, 2004 issue, the title and a portion of the abstract were modified incorrectly by the printer. The title should read “Phosphatidylinositol 4,5-Bisphosphate Signals Underlie Receptor-Specific Gq/11-Mediated Modulation of N-type Ca2+ Channels.” In the third sentence of the abstract, PIP2 should be defined as phosphatidylinositol 4,5-bisphosphate.
