(Neuron 82, 872–886; May 21, 2014) In the original article, there was an error in the two-sample Kolmogorov-Smirnov statistical testing of firing rate changes. The corrected p values changed the evaluation of individual cells under certain behavioral and network states but do not change the conclusions of the paper for the overall population of a given cell type. The legend to Figure 5 (F and G) should say that the measured distribution of the O-LM cell was similar to the median (black) of the surrogate set (p = 0.9, during sleep; p = 0.4, during wakefulness; two-sample KS tests), the legend to Figure S4 should say that three O-LM cells (B) changed their firing rates significantly during sleep SWRs (two-sample KS-tests, n = 3 cells in total, p < 0.05, for all cells) and for cells LK06ah and LK13k in the awake condition, the measured rates were similar to those expected from the surrogate sets, whereas, the rate of ZsB43d was lower than expected (two-sample KS-tests, LK06ah, p = 0.2; LK13k, p = 0.1; ZsB43d, p < 0.05), and the last paragraph of the Results section should say that during wakefulness, the firing rate during SWRs was significantly lower for one O-LM cell and higher for the other three cells than that expected (CDFs p < 0.05 for n = 4 cells; Figures 5G and S4B and Table 2). The authors regret the error and any confusion this may have caused.
