In the article “A TrkB Small Molecule Partial Agonist Rescues TrkB Phosphorylation Deficits and Improves Respiratory Function in a Mouse Model of Rett Syndrome” by Danielle A. Schmid, Tao Yang, Michael Ogier, Ian Adams, Yatin Mirakhur, Qlfang Wang, Stephen M. Massa, Frank M. Longo, and David M. Katz, which appeared on pages 1803–1810 of the February 1, 2012 issue, one of the authors failed to disclose a financial conflict of interest.
