Figure 4From: Dynamic optimization of distributed biological systems using robust and efficient numerical techniquesThe figures at the top show two snapshots of the v -field for the FHN system corresponding to (a) the front behavior and (b) the spiral behavior. The figures at the bottom represent the v-field cross section at Îľ2 = 100 and at different times corresponding to (c) the front behavior and (d) the spiral behavior.Back to article page
