Figure 4A visualizes both the decay rate constant μ_i (left panel) and the ratio ${\tau }_i^0∕{\mu }_i$ (right panel) neuroanatomically using top views for all 4 parcellation schemes on the brain surface of a representative subject. Note that visually trends are consistent across all schemes, showing both a posterior-to-anteriro gradient and a medial-to-lateral gradient for μ_i and ${\tau }_i^0∕{\mu }_i$ (the gradients are increasing for decay rate μ_i and decreasing for the ratio ${\tau }_i^0∕{\mu }_i$). Figure 4B visualizes the embeddedness, as a heat map, on a Freesurfer-defined group average cortical surface using the 82-parcellation scheme.
