Convergent stimulation results in coherent migration response towards the center. Representative kymograph of Vx averaged across x-position in a control (A) and stimulated (D) tissue pair. The control tissues expand uniformly outwards, while the stimulated tissues converge towards the cathode with uniformly high speed across the tissue area (~60 μm/h directed towards the gap). Horizontal velocity maps (B,E) and migration maps (C,F) in representative tissue pairs.
