In the article “Direct brain recordings reveal prefrontal cortex dynamics of memory development,” the authors corrected an error in data preprocessing that enriches the analysis of the work.

Figure 1B was corrected to show the distribution of 301 active electrodes instead of the original 295. Figures 2 and S1 were updated to reflect this change.

The following sentences on page 3 were updated for correctness:“As shown in Fig. 2, per-trial cortical activity exhibited subsecond propagation from PCG, where it receded the encoding response, to SFG, MFG, and IFG sites, where it appeared more sustained throughout the 3-s scene presentation epoch (z > 2.57, P < 0.01).” was changed to “As shown in Fig. 2, per-trial cortical activity was evident in all frontal subregions, with the most pronounced activity preceding the response onset (z > 2.57, P < 0.01).”The sentence, “We note that these patterns were evident even in the two youngest subjects (6.2 and 8.5 years of age), who showed broadband peak activity that was significantly timed to the encoding response at all MFG and PCG sites (FDR-corrected P < 0.05; Fig. 2, A and B, and fig. S1, A and B). (There was no IFG or SFG coverage in these subjects.)” was changed to “We note that these patterns were evident in both the youngest and oldest subjects (6.2 and 19.4 years of age), who showed broadband peak activity that was significantly timed to the encoding response at all sites sampled (FDR-corrected P < 0.05; Fig. 2, A and B, and fig. S1, A and B).”

The corrections do not impact the conclusions of the paper. The HTML and PDF versions have been updated.
