Publisher Correction Published: 11 May 2026 Nature ( 2026 ) Cite this article Subjects Correction to: Nature https://doi.org/10.1038/s41586-021-03369-7 Published online 24 March 2021 In the version of this article initially published, in Fig. 4d, data points were inadvertently omitted from the far-right Rett early training (MeCP2–) bar in the process of figure formatting by the journal. Separately, in Extended Data Fig. 6a, the image shown in the lower-left Rett mCherry panel mistakenly presented an image from Rett-hM3Dq Cortex. Also, three out of four Cortex panels in Extended Data Fig. 7 were mislabeled as “GFP” when they should have been labeled “cFos”. The figures are now amended in the HTML and PDF versions of the article.
