Correction to: Nature Neuroscience https://doi.org/10.1038/s41593-019-0531-z, published online 25 November 2019.

In the version of this article initially published, graphical errors occurred when plotting individual data points: in Fig. 1e, the same data points were accidentally plotted over two adjacent bars; in Extended Data Fig. 5a, dots were switched between adjacent bars. All means and standard errors were plotted correctly, and all data analysis and statistics were done on the correct sets of data. The errors have been corrected in the HTML and PDF versions of the article.
