Correction
When the October 2012 issue was posted online October 2, the PDF that accompanied the online version of the article “Presupplementary Motor Area Hyperactivity During Response Inhibition: A Candidate Endophenotype of Obsessive-Compulsive Disorder,” by Stella J. de Wit, M.D., et al. (Am J Psychiatry 2012; 169:Original article: 1100–1108), contained an older version of Figure 3. The figure did appear as intended in the online and print editions of the article, and on October 5, 2012, the correct PDF was uploaded to accompany the article.
