(A) n:m phase-locking levels for actual hippocampal LFPs (same dataset as in Figure 5). Theta phase was estimated by the interpolation method described in Belluscio et al. (2012). (B) Original and surrogate distributions of Rn:m values. The original data are significantly higher than surrogate values obtained from pooled Δφnm, but indistinguishable from single run surrogates. *p<0.01, n = 7 animals, Friedman’s test with Nemenyi post-hoc test.
