Resting-state functional connectivity maps from monkey areas 9/46d and 31. A, B, Brain regions showing correlated activity with areas 9/46d (A) and 31 (B) are illustrated on an inflated cortex. The seed area is indicated with the red label. Correlation values are shown using a color scale indicating the statistical significance.

Resting-state functional connectivity maps from monkey areas 8b and v23. A, B, Brain regions showing correlated activity with areas 8b (A) and v23b (B) are illustrated on an inflated cortex. The seed area is indicated in red. Correlation values are shown in color scale based on the statistical significance.

Network of consistent task-related deactivations in the monkey brain. A, B, Brain areas deactivated (p < 0.01) in at least 8 of the 15 monkey task-related experiments are illustrated in inflated cortical representations (lateral and medial views) (A) and on flat maps (B). The areas are labeled on the flat maps on the basis of the monkey brain atlas by Paxinos et al. (2008).

Functional subdivision of the monkey default-mode network. A, Network analysis on resting-state connectivity is performed using the Kamada–Kawai algorithm. Only significant correlations at p < 0.001 are plotted in the graph. The thickness of the lines reflects the strength of the correlation between regions. The size of the circles represents a measure of betweenness-centrality. The two regions with the betweenness-centrality above average, areas 9/46d and 31, are considered DMN hubs. B, Hierarchical cluster analysis on the remaining connected regions reveals that the monkey DMN is additionally comprised of two distinct subsystems including areas 24/32, 8b, and TPOC and areas 23, v23, and PGm, respectively. C, Selectivity in the deactivation (in percentage signal change, PSC) across multiple experiments is revealed for the network core and its subsystems. The groups of experiments for which the deactivation is significant at p < 0.001 are marked with asterisks in the plot.

Comparison of monkey (A) and human (B) default-mode network foci. The monkey DMN obtained from our meta-analysis (as shown in Fig. 1) is spatially compared with a representative human DMN (adapted from Laird et al., 2009). The latter was obtained by a coordinate-based meta-analysis of deactivation peaks across a large number of published human fMRI studies, using the activation likelihood estimation (ALE) method (see Laird et al., 2009 for more details). The ALE map was thresholded at p < 0.005, corrected with false discovery rate. The monkey and human DMNs are represented on an anatomical template (F99 and MNI, respectively) in selected axial and sagittal sections. The illustrated foci are classified on the basis of cytoarchitectonic mapping studies. The monkey and human DMNs are spatially comparable, but not necessarily the same in amplitude, as they have been obtained using different datasets and different statistical approaches.
