Figure Lengend Snippet: (A–H) Bar plots of peak inter-areal correlation coefficients (r values) of six ROI pairs in delta (A), theta (B), alpha (C), beta (D), gamma low (E), gamma high (F), gamma very high (G), and broad (H) frequency bands. Error bars indicate standard error of the mean (SEM; N=33). Differences between inter-areal connections calculated via Dunn’s multiple comparison test post Friedman’s test, (* p<0.05, ** p<0.001, *** p<0.001). All LFP bands, with the exception of the theta band, displayed similar correlation profiles as fMRI data presented in Figure 1B.

Article Snippet: Dunn’s multiple comparison test was used to compare the mean rank of each area pair that was obtained from Friedman’s test, a non-parametric statistical test similar to the repeated measures ANOVA, in GraphPad Prism version 5.04 for Windows (GraphPad Software). fig ft0 fig mode=article f1 fig/graphic|fig/alternatives/graphic mode="anchored" m1 Open in a separate window caption a7 caption a8 Representative correlation coefficient and lag plots of instantaneous amplitudes of different ROI pairs from one subject This figure shows correlation coefficient plots of the delta (1–4 Hz) power band of instantaneous amplitudes populated via the Hilbert transform ( Adhikari et al., 2010 ).
