In the article “Oscillatory Reinstatement Enhances Declarative Memory” by Amir-Homayoun Javadi, James C. Glen, Sara Halkiopoulos, Mei Schulz, and Hugo J. Spiers, which appeared on pages 9939–9944 of the October 11, 2017 issue, the authors regret a typo in Figure 1. The error in Figure 1a had the duration indicated as 6 h, but should be instead listed as 1.5 h, as also stated in the Procedure subsection on page 9940. This correction does not affect the conclusions of the paper. Figure 1 has been corrected in the online PDF version and is displayed below.
