A Multi-modal Parcellation of Human Cerebral Cortex


Figure 5

Figure 5 shows the four feature categories and their gradients.  Rows 1 and 2 show inflated and flat map views of cortical myelin maps and gradients.  Rows 3 and 4 show cortical thickness maps with curvature regressed out and their gradients.  Rows 5 and 6 show an example task contrast effect size map (scaled to beta = +/-0.8) and its gradient from the LANGUAGE Story vs Baseline contrast.  Task fMRI effect size maps can be treated similarly to the architectural myelin and thickness measures as far as gradient computation is concerned.  Rows 7, 8, and 9 show three functional connectivity maps from the white spheres representing seed locations in FEF, 55b, and PEF (Row 7 is the most dorsal, Row 8 is the middle, and Row 9 is the most ventral).  Row 10 shows the mean functional connectivity gradient map.  Note that as one crosses the strong gradients surrounding area 55b from FEF to 55b to PEF, the functional connectivity pattern changes dramatically.  This is correlated with smaller changes in myelin density (moderate to light to moderate, See Main Results).  Also, note that the functional connectivity map from the 55b seed (Row 8) strongly resembles the LANGUAGE Story task activation map (Row 5).
