Figure 2. Position and extent of the prefrontal areas on the medial, lateral, and orbital views of the Yerkes19 surface.

The files with the parcellation scheme are available via EBRAINS platform of the Human Brain Project (https://search.kg.ebrains.eu/instances/Project/e39a0407-a98a-480e-9c63-4a2225ddfbe4) and the BALSA neuroimaging site (https://balsa.wustl.edu/study/7xGrm). Macroanatomical landmarks are marked in red letters, while black dashed lines mark fundus of sulci. arcs, spur of the arcuate sulcus; cgs, cingulate sulcus; cs, central sulcus; ias, inferior arcuate sulcus; lf, lateral fissure; ps, principal sulcus; sas, superior arcuate sulcus.

(C) Macaca mulatta template brains. arcs, spur of the arcuate sulcus; asd, anterior supracentral dimple; aspd, anterior superior principal dimple; cs, central sulcus; ias, inferior arcuate sulcus; ps, principal sulcus; pspd, posterior superior principal dimple; sas, superior arcuate sulcus; spcd, superior precentral dimple.

Areas are labelled on the left hemisphere, that is, prefrontal areas in black and previously mapped (pre)motor areas (Rapan et al., 2021) in grey. Due to limited space on the map, we used white arrows to mark anterior and posterior subdivisions of 46. Dashed yellow line on the hemispheres represents the midline, which separates medial and dorsolateral cortex. Black full lines mark the fundus of sulci. Macroanatomical landmarks are marked on the right hemisphere; arcs, spur of the arcuate sulcus; asd, anterior supracentral dimple; aspd, anterior superior principal dimple; cgs, cingulate sulcus; cs, central sulcus; ias, inferior arcuate sulcus; ipd, inferior principal dimple; lf, lateral fissure; lorb, lateraral orbital sulcus; morb, medial orbital sulcus; ps, principal sulcus; pspd, posterior superior principal dimple; sas, superior arcuate sulcus; spcd, superior precentral dimple.
