In the version of this article initially published, the title of ref. 45 was given as “Sustaining cortical representations by a content-free thalamic amplifier.” The correct title is “Thalamic amplification of cortical connectivity sustains attentional control.” The error has been corrected in the HTML and PDF versions of the article.
