Flow diagram of the study. ① The FIC and dACC defined by HCP rfMRI dataset were used as the seeds to track the fiber bundles in the Chinese young cohort. ② The fiber probability map created using the HCP dMRI dataset was used to extract the FA values along the right FIC‐dACC fiber trajectory in the Chinese elder cohort. Abbreviations: dACC, dorsal anterior cingulate cortex; dMRI, diffusion magnetic resonance imaging; FA, fractional anisotropy; FIC, frontoinsular cortex; HCP, human connectome project; FIC, frontoinsular cortex; rfMRI, resting‐state functional magnetic resonance imaging; SN, salience network
