“…In contrast, existing methods to construct brain structural network are mainly white matter tractography (Li et al, 2009;Koenis et al, 2018) and structural covariance network (Mechelli et al, 2005;Alexander-Bloch et al, 2013). As stated in our previous study (Li et al, 2021), the white matter tractography could not reliably quantify long-range structural connectivity (Jeurissen et al, 2019) and was largely affected by head motion and might involve a large number of false-positive connections (Thomas et al, 2014;Maier-Hein et al, 2017); the structural covariance network from a large number of participants only yielded one single correlation matrix but did not reveal individual differences (Alexander-Bloch et al, 2013;Li et al, 2021). Therefore, in this study we still used macroscale morphology network that was based on distributions of cortical surface characteristics (cortical volume, thickness, and surface area) from resting-state fMRI (Li et al, 2021) in order to explore the neural substrates of state and trait anxiety.…”
