Correction to: Nature Neuroscience, published online 25 May 2020.

In the version of this article initially published, the vertical axes were mislabeled in Fig. 6b, and a horizontal dashed line indicating P = 0.001 was omitted from the right-hand graph in Fig. 6c. The errors have been corrected in the HTML and PDF versions of the article.
