In the article “AMPA Receptor-Induced Local Brain-Derived Neurotrophic Factor Signaling Mediates Motor Recovery after Stroke” by Andrew N. Clarkson, Justine J. Overman, Sheng Zhong, Rudolf Mueller, Gary Lynch, and S. Thomas Carmichael, which appeared on pages 3766–3775 of the March 9, 2011 issue, the authors regrettably noted incorrect Cresyl Violet photographs, which were included as representative images in Figure 9. These images have now been replaced with the correct images on the online PDF version and displayed below. This correction does not affect the conclusions of the paper.
