Figure 5.

β ₀‐plots between PET and MRI of (a) ADHD, (b) ASD, and (c) CON on the ∈ − γ plane. The vertical axis represents a mixing ratio γ and the horizontal axis represents a new threshold ∈ on the projection line with mixing ratio γ The color in β ₀‐plot in (a,b) is varied according to the zeroth Betti number β ₀ between 1 and the number of nodes P = 93_. When β ₀ becomes larger, the color changes from white to dark red as shown in the right colorbar. [Color figure can be viewed at http://wileyonlinelibrary.com]
