“…Therefore, various groups (including ours) have most frequently utilized the 400-region Schaefer group-level parcellation (Varikuti et al, 2018; Franzmeier et al, 2019; Kebets et al, 2019; Murphy et al, 2020; Orban et al, 2020). Other studies have opted to utilize different resolutions of the Schaefer group-level parcellation, e.g., 100 regions (Chin Fatt et al, 2019), 200 regions (Anderson et al, 2020; Faskowitz et al, 2020) and 800 regions (Valk et al, 2020). Despite our focus on the 400-region areal-level parcellations in the current study, we do not believe that there is an optimal number of cortical parcels because of the multi-resolution organization of the cerebral cortex (Churchland and Sejnowski, 1988; van den Heuvel and Yeo, 2017).…”
