FIGURE 3

Brain surface (cortex) and volume (subcortex) visualizations of brain networks/groups with above‐threshold reliability in at most five of the six jhanas (where jhanas J6–J8 are merged). Changes in the lower confidence limits of brain network ICC across the jhanas in each of these distinct networks/groups are depicted graphically alongside their brain maps. (a) The 16 brain networks/groups with above‐threshold reliability (ICC lower confidence limit ≥0.75) in at most five jhanas have been shown on the brain using distinct colors labeled in panel (b). (b) Change in the lower confidence limit of brain network ICC across jhanas in each of the 16 networks/groups relative to one another, where ICC change of only the labeled network/group is highlighted (black line) in each graph while the remaining networks/groups are grayed out in the background. The network/group label above each graph is accompanied by its respective color as shown on the brain map in panel (a). The y‐axis of each graph represents brain network ICC values while the distinct jhanas (J1 to J6–J8) are marked on the x‐axes. (c) Similar to (a) showing 14 brain networks/groups after controlling the region‐level ReHo values for key self‐report phenomenological variables (1 value per fMRI run per jhana) including “Attentional stability,” “Attentional width,” and “jhana intensity.” (d) Similar to (b) after controlling the region‐level ReHo values for the same self‐report phenomenological variables. The network/group label above each graph is accompanied by its respective color as shown on the brain map in panel (c). In each graph of (b) and (d), the dotted red line represents the threshold of “good” brain network ICC (i.e., ICC lower confidence limit of 0.75). The green colored points indicate above‐threshold ICC (i.e., ICC lower confidence limit ≥0.75) while red colored points indicate below‐threshold ICC (i.e., ICC lower confidence limit <0.75) for a given jhana. A, anterior; fMRI, functional magnetic resonance imaging; ICC, intraclass coefficient correlation; L, left; P, posterior; R, right; ReHo, regional homogeneity.
