In the article, “G2019S-LRRK2 Expression Augments α-Synuclein Sequestration into Inclusions in Neurons,” by Laura A. Volpicelli-Daley, Hisham Abdelmotilib, Zhiyong Liu, Lindsay Stoyka, João Paulo Lima Daher, Austen J. Milnerwood, Vivek K. Unni, Warren D. Hirst, Zhenyu Yue, Hien T. Zhao, Kyle Fraser, Richard E. Kennedy, and Andrew B. West, which appeared on pages 7415–7427 of the July 13, 2016 issue, the description of Figure 8D requires clarification. The authors state: “Regarding Figure 8, the representative images at the different magnifications were not necessarily from the same sections, or even from the same animals, but they were representative to the best of our ability.” This clarification does not affect the conclusions of the paper.
