“…Interestingly, the probability maps also reveal that the location of the SFS shows variability across subjects, which may result from its high likelihood of merging with a surrounding frontal sulcus (see Tables 1 and 2, and maximum probability values in Figures 3–6). Previous qualitative analyses of the SFS have consistently described the morphological variations of this sulcus (see Section 4.1), particularly in comparison to the classic sulcal maps (see Figure 2; Eberstaller, 1890; Cunningham, 1905; Bailey & Bonin, 1951; Connolly, 1950; Ono et al, 1990; Juch et al, 2005; Ribas et al, 2006; Gonul et al, 2014). This inter‐individual morphological variability is significant given that it is maintained despite linear registration of brains to the axes of MNI standard stereotaxic space for morphological analyses (Drudik et al, 2023; Sprung‐Much & Petrides, 2018, 2020; Zlatkina et al, 2022).…”
