“…The exact link between the folding pattern and functional competence is a complex issue (Welker et al, 1988 ; Zilles et al, 2013 ). However, strong correspondences between cortical folding features and functional activations have been found not only in primary areas but also in higher level areas, including the visual areas (Watson et al, 1993 ; Dumoulin et al, 2000 ), the paracentral sulcus (Grosbras et al, 1999 ), the PreCS (Sun et al, 2015 ), the frontal operculum (Amiez et al, 2016 ), the midcingulate cortex (Amiez et al, 2013 ), the dorsal premotor region (Amiez et al, 2006 ) and the fusiform gyrus (Weiner et al, 2014 ). The main difficulty limiting the investigation of such sulcal morphology/function correspondence is the variability of the folding pattern (Ono et al, 1990 ; Régis et al, 2005 ; Petrides et al, 2012 ).…”
