Correction to: Nature Neuroscience https://doi.org/10.1038/s41593-018-0271-5, published online 26 November 2018.

In the version of this article initially published online, Fig. 1f,g contained errors: in panel G, the axes for d ′ were erroneously displayed as vertical rather than horizontal; and the labels “Monkey” and “Model” in panel F should have been vertically oriented rather than diagonally. The error has been corrected in the PDF and HTML versions of this article.
