In the article “Spinocerebellar Ataxia Type 6 Protein Aggregates Cause Deficits in Motor Learning and Cerebellar Plasticity” by Melanie D. Mark, Martin Krause, Henk-Jan Boele, Wolfgang Kruse, Stefan Pollok, Thomas Kuner, Deniz Dalkara, Sebastiaan Koekkoek, Chris I. De Zeeuw, and Stefan Herlitze, which appeared on pages 8882–8895 of the June 10, 2015 issue, the authors regret an error in Figure 7C, right panel. The color of the data points in the line graph for the fl-CT-longQ27 and the CT-longQ27PC were accidentally switched. The correct Figure 7 is shown on the next page.
