Figure 5. Critical length of the minimal substrate size for re-entry (MS) in 2D sheets.

Aa and b, Ba and b, illustration of MS required to induce a pair of re-entrant circuits in homogeneous 2D sheets. C, critical length under WT, ϕ= 0.1, ϕ= 0.25 and ϕ= 1 conditions. The critical length under mutant conditions was dramatically shorter than under Control conditions.
