Target Patterns Cardiac cells in monolayer cultures older than two days often generate periodic target patterns of activity. Spiral waves Cells in monolayer cultures younger than two days often form spirals. This record was obtained using a voltage sensitive dye. Pharmacological gap junction block changes the spatiotemporal characteristics of the spiral waves.
Simulation results A cellular automata simulation of the heptanol results.
