51, p < 0.001, pη2 = 0.69). The increased correlation between visual and language this website nodes was stronger in θ with respect to α and δ (all p values < 0.001) and γ (p < 0.02), and in β with respect to α (p < 0.01), δ (p < 0.001) (Figure S6D). The comparison between β and θ and between β and γ did not reach significance (all p values > 0.05). Same results were

obtained using nodes based on the maps of Figure 3 (Figure S5A). In contrast, correlation decreased more strongly for α BLP during movie with respect to fixation between visual and auditory nodes (all p values < 0.001) (Figure S6E) and between visual and dorsal attention nodes (Figure S6F) (all p values < 0.001). In summary, regions in the visual network decrease their α BLP interaction with regions in the dorsal attention network but increase their BLP interaction in β, θ, and γ with regions in the language network. Next, we consider modulation in the default-mode network with respect to sensory and attention networks (Figure 6). Within-DMN BLP correlation dropped specifically in the α band during

the movie condition as compared to fixation. With respect to cross-network interaction, α BLP correlation decreased between DMN and auditory and dorsal attention, while β BLP correlation GW786034 in vitro decreased between DMN and auditory networks. However, the DMN increased correlation with the language network in the γ band. In summary, the default-mode network showed a pattern of BLP correlation modulation similar to other sensory and attention networks including decrements of within- and across-network interaction in the α band and increased interaction with the language network at higher (γ) frequencies. Control analyses were also carried out to examine the robustness of the results in relation to possible decreases in signal-to-noise due to α power decreases produced by visual stimulation in the movie condition (Berger, 1929; Supplemental Information and Figures S5B and S5C) and at the level of single subjects (Figures S5D and S5E).

One of the most influential observations shaping the debate on the function of RSN is that their topography is similar to that Oxymatrine of task networks (Biswal et al., 1995, Greicius et al., 2003 and Smith et al., 2009). This has suggested that RSN may be a prior for task-driven patterns of activity (Raichle, 2011). Inspection of the covariance matrix for fMRI connectivity vis-à-vis MEG BLP correlation in different bands (Figure 5) and by network (Figure 6), shows significant decreases of fMRI connectivity during movie within visual (t test: p < 0.005) and dorsal attention networks as well as between networks (visual-auditory [p = 0.003]; visual-dorsal attention RSN [p < 0.001]). Functional MRI connectivity decreases qualitatively parallel α and β BLP correlation decreases within and across networks earlier described.
