Relationship between Functional and Anatomical Variability (image) Cell Press Share Print E-Mail Caption Functional connectivity variability is significantly associated with the variability in sulcal depth (A) but not the variability in cortical thickness (B). Intersubject anatomical variability was calculated using intraclass correlation (ICC), with the intrasubject variance properly accounted for. Sulcal depth variability showed a significant correlation with functional variability (r = 0.30, p < 0.0001) while cortical thickness variability was uncorrelated with functional variability (r = 0.05, p > 0.05).
