ICN, Intrinsic Connectivity Network; ICC, intraclass correlation coefficient; REF, Reference Sample; three Reference Sample masks were used for ICCs and summary statistics. 1) full ICN mask represented the group-level ICN connectivity map z ≥ 6. 2) “Connectivity Cores”: full ICN mask was rethresholded to only included voxels above the 75th connectivity percentile within original map z ≥ 6. 3) “Reliability Cores”: full ICN mask was rethresholded to only included voxels above the 75th ICC percentile within the original map z ≥ 6. ICC lower than 0.40 is considered ‘poor’, 0.40 – 0.58 is considered a ‘fair’ level of agreement, 0.59 – 0.75 is considered ‘good’ agreement, 0.76 and above is considered ‘excellent’ agreement (Cicchetti & Sparrow, 1981). Bold values indicate statistic greater than or equal to 0.40.
