Correction to: Nature https://doi.org/10.1038/nature20587, published online 07 December 2016.

In Extended Data Fig. 8 of this Article, we inadvertently copied the data between Aβ1–40 levels at 1 h and Aβ1–42 levels at 1 h. We have corrected the Aβ1–42 graph and re-run the statistical analysis. We see a significant reduction in Aβ1–40 and Aβ1–42 levels 1 h after 40 Hz flicker, consistent with the other independent replications in the Article and with our immunohistochemistry analysis of Aβ plaques. Our overall findings and conclusions are not changed by these results. We also accidentally omitted the raw ELISA data values for Aβ1–40 and Aβ1–42, for ‘Dark 1hr’ and ‘40 Hz 1 hr wait 1 hr’ in Extended Data Table 1. The Supplementary Information to this Amendment contains the old, incorrect Extended Data Fig. 8 and Extended Data Table 1, for transparency. These errors have been corrected online.
