Correction to: Nature Neuroscience https://doi.org/10.1038/s41593-018-0296-9. Published online 7 January 2019.

We have identified an accidental duplication of the representative image of IBA1 stain in Supplementary Fig. 2a (APPPS1/TREM2–/– and APPPS1/TREM2p.T66M) as well as a miscalculation of the scale bar in the merged images. We greatly apologize for these errors and are now providing a corrected version of the figure (see Fig. 1 below). Please note that none of the conclusions of the manuscript are affected.
