Intrinsic functional connectivity of cortical midline regions previously demonstrated to play a role in self-referential cognition is associated with self-related information sharing on social media across participants.
(A) Connectivity of the MPFC and the CP to the right DLPFC is positively associated with self-related sharing score across participants (connectivity to Seed 1 in the MPFC = red, Seed 2 in the CP = blue). Overlap in the right DLPFC between results from MPFC and CP is 22 voxels (purple). Plots depict participants’ resting-state activation correlations between either the MPFC or CP and the right DLPFC with respect to their self-related sharing scores. (B) Connectivity of the CP to the left lateral OFC is positively associated with self-related sharing score across participants. Plot depicts participants’ resting-state activation correlations between the CP and the left lateral OFC with respect to their self-related sharing scores. (C) Connectivity of the CP to the left ATP is negatively associated with self-related sharing score across participants. Plot depicts participants’ resting-state activation correlations between the CP and the left ATP with respect to their self-related sharing scores. All results are whole-brain FWE cluster-level corrected at p < 0.05 after setting the voxel-level uncorrected threshold to p < 0.001. All scatter plots are solely for illustrative purposes (e.g., to show the absence of outliers) and are not used for statistical inference.
