“…While considerable research has used temporal coupling of BOLD signals (i.e., FC) to reveal information exchange among brain areas (Jiang et al, ; Jiang, Luo, Gong, Peng, et al, ; Zhu et al, ), rich high‐order information interactions such as dynamic (He et al, ; Hutchison et al, ; Klugah‐Brown et al, ), causal (Chen, Jiang, et al, ; Jiang, Luo, Li, Duan, et al, ), hierarchical (Smith et al, ), and many‐to‐many (Pessoa, ) have not been fully explored yet. To characterize a complex relationship between white‐matter and gray‐matter regions, this study measured the functional resemblance between any two white‐matter networks based on their connectivity profiles with gray‐matter regions.…”
