Fig. 2: Cortico-cortical functional connectivity within the allostatic–interoceptive system.
From: Cortical and subcortical mapping of the human allostatic–interoceptive system using 7 Tesla fMRI
a, Left column shows cortical seed locations and right column shows group-level t-value maps (n = 90) masked by voxels that showed positive connectivity (two-tailed t test, P < 0.05) with the seed in more than 950 iterations (of 1,000) by resampling 80% of the sample in each iteration (n = 72). b, Seed-to-seed functional connectivity matrix shows connectivity strength between each pair of the cortical seeds (two-tailed t test, P < 0.05, uncorrected; white color indicates correlation = 1; n = 90). c, The allostatic–interoceptive system showed connecting regions in all the a priori interoceptive and visceromotor control regions. Connecting regions belonging to the ‘rich club’ are labeled in yellow. ‘Rich club’ hubs image in panel c is adapted with permission from ref. 105. lvAIns, lateral vAIns; mIns, mid insula; mvAIns, medial vAIns.
