Connectivity in the “Obligatory” (yellow) and “Optional” (green) nodes of the face network.

<p>Thickness of lines indicates proportion of participants (%) with a given pair-wise connection, defined as a pair-wise correlation r>0.3. Yellow and green lines denote connections within the “Obligatory” and “Optional” networks, respectively. Red lines denote connections across the two subnetworks; for clarity, only connections present in 50% or more participants are shown. For all pair-wise values, see Supplementary <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004523#pgen.1004523.s005" target="_blank">Table S2</a>. 1, mid-ventrolateral frontal cortex (right); 2, mid-dorsolateral frontal cortex (left); 3, premotor cortex (left); 4, anterior portion of the superior temporal sulcus (right); 5, posterior portion of the superior temporal sulcus (right); 6, fusiform face area (right); 7, lateral occipital cortex (left); 8, lateral occipital cortex (right). LEFT, the left hemisphere; RIGHT, the right hemisphere. The flat maps of the cerebral cortex contain the probability map of the face network adapted from Tahmasebi et al. <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004523#pgen.1004523-Tahmasebi1" target="_blank">[13]</a>.
