Template surface construction

Using both labelled and unlabelled datasets, we derived group-averaged white (Fig. 8(i)), pial (ii), and inflated surfaces (iii) along with curvature (iv) and sulcal depth maps in a common spherical space. For interoperability with the dHCP and UNC atlases^14,23, we also provide versions of the M-CRIB-S spherical template surfaces registered to the dHCP 42-week and UNC 42-week spherical template surfaces. M-CRIB-S(DKT) and M-CRIB-S(DK) parcellation maps in each labelled subject were transferred to the spherical template and used as the training set for the FreeSurfer tool mris_ca_label. We applied this labelling to the average white matter surface using the M-CRIB-S(DKT) to illustrate our cortical labelling approach (Fig. 8(i–iii)). For comparison, the M-CRIB-S(DK) labelling is also shown (Fig. 8(v)). These group-average label images may be used for display of statistical analysis results using the M-CRIB-S(DKT) or M-CRIB-S(DK) atlases.

Average white (i), pial (ii), and inflated (iii) left (LH) and right hemisphere (RH) surfaces for all subjects with the vertices coloured according to M-CRIB-S(DKT) labels. The average white matter curvature map is shown on the inflated surfaces in (iv). The lateral view of the M-CRIB-S(DK) atlas is shown in (v). The annotations in panel (iii) and (v) highlight selected differences between the atlases. The white ellipses focus on the lateral orbitofrontal and pars orbitalis regions. The black ellipses centre on the bank of the superior temporal sulcus (BSTS), which is absent in the M-CRIB-S(DKT) atlas. BSTS: Banks of the superior temporal sulcus, CAC: Caudal anterior cingulate, CMF: Caudal middle frontal, CUN: Cuneus, ENT: Entorhinal, FP: Frontal pole, FUS: Fusiform, INFP: Inferior parietal, INS: Insula, ISTC: Isthmus cingulate, IT: Inferior temporal, LIN: Lingual, LOCC: Lateral occipital, LORB: Lateral orbitofrontal, MORB: Medial orbitofrontal, MT: Middle temporal gyrus, PARH: Parahippocampal, PARC: Paracentral lobule, POPE: Pars opercularis, PORB: Pars orbitalis, PCING: Posterior cingulate, PCAL: Pericalcarine, POSTC: Posterior cingulate, PCUN: Precuneus, PREC: Precentral, PTRI: Pars triangularis, RAC: Rostral anterior cingulate, RMF: Rostral middle frontal, SF: Superior frontal, SMAR: Supramarginal gyrus, SP: Superior parietal, ST: Superior temporal gyrus, TP: Temporal pole, TT: Transverse temporal gyrus.
