Following the publication of our article, we were made aware of errors in the presentation of the data in Figures 4 and 5. (Figure presented.) A whole-brain voxel-wise analysis revealed a significant interaction between delay and group in several regions including the right DLPFC and inferior parietal lobule (a). fMRI activation decreased across a 12-hr delay for the sleep group but increased for the wake group (b) in both regions [Color figure can be viewed at wileyonlinelibrary.com] Figure 4 caption should read: fMRI activation changes over a 12-hr delay in anatomically defined hippocampal subfields. There was a significant change in activation with a decrease for LureFA and an increase for LureCR in the CA1 and subiculum. **p <.01; *p <.05 Figure 5b Y-axis is inverted. We provide a corrected figure here (Figure 1 above). Section 4.2, second paragraph should read: We observed a decrease in hippocampal activation for the LureCR trials and an increase for LureFA trials following a 12-hr delay. Although this pattern of activation change was present in the CA3/DG, the change in activation was significant in the CA1 and subiculum only. As correct responses to lure stimuli (i.e., LureCRs) are thought to tax pattern separation processes (Kirwan and Stark, 2007), it might be expected that an increase in LureCR related activity would be consistent with an increase in pattern separation processing over a 12-hr delay. Instead, we observed increased activity for LureFAs, consistent with an increase in task demand over a 12-hr delay. Contrary to our hypotheses, however, this change in activation was not modulated by sleep, as both sleep and wake groups displayed this change in activation.
