SCENE:
Gradients in the connectivity profile

DESCRIPTION:
Figure 9A-E

For a single subject and group average illustrates the gradient of the connectivity profile when tracking from the cortex to the deep WM. The image shows the dissimilarity of the path streamlines seeded from each vertex take with respect to their neighbour. Hotter colours indicate more dissimilar paths (i.e., a stronger gradient in the connectivity profile).

Across all the tabs we have:
A. dissimilarity when seeding from white/grey matter boundary for single subject (note the regions with high dissimilarity align with the sulcal fundi and gyral crowns). Change the selected map to view a different subject.
B. Across-subject average of A. Change the selected map to view a single subject.
C. dissimilarity when seeding from deep/gyral white matter interface for single subject (you can jump through all the subjects by adjusting the map). Change the selected map to view a different subject.
D. Across-subject average of B. Change the selected map to view a single subject.
E. Single-subject sulcal depth map

Tractography was seeded from either the white/grey matter boundary (top) or the deep/gyral WM interface (middle) and the connectivity from each vertex to the voxels in a deep white matter mask were stored.
