Correction to: Nature https://doi.org/10.1038/s41586-022-05439-w Published online 16 November 2022

In the version of the article initially published, the “Isolation of nuclei from frozen post-mortem brain tissue” and “Droplet-based snRNA-seq” sections of the Methods did not reference a partial overlap of human snRNA-sequencing samples with samples reported in a previous study1 (ref. 12 in the original article). Raw data corresponding to 8 of the 32 samples reported were taken from the previous study and reprocessed together with the newly generated data. The Methods have now been updated in the HTML and PDF versions of the article to reflect this clarification.
