Fig. 5From: Transient Localized Wave Patterns and Their Application to MigraineAn example of a transient solution. Initial conditions, i.e., activator concentration u at 0 sec (upper left), snapshot of activator-concentration u after 30 sec (upper right), after 180 sec (lower right). Time of passing through threshold value u 0 =0 from below the first time, i.e., passing of the wave front (lower left)Back to article page
