Fig 3. Front propagation in secondary tauopathy; rectangular domain.

Each subfigure consists of a toxic Aβ concentration distribution (top left), toxic τP concentration distribution (bottom left) and a plot (solid line: Aβ, dashed line: τP) of the concentration level on the x−axis. Dark blue indicates the minimum concentration of c = 0.0 while bright red indicates the maximum of c = 0.5 for toxic Aβ and $c=0.58\overline{3}=7/12$ for toxic τP. See the Methods section (Front propagation) for a comparison to theory. (See also: supplementary S3 Video).
