Figure 7.
Ca signaling hierarchy reproduced by the Ca cycling model. At t = 0 ms there are quarks (q), sparks (s), and clusters of sparks (c), commonly referred to as macrosparks. The cluster of sparks (c) at t = 0 ms eventually evolves into a Ca wave (w) by t = 120 ms. Note that it is a random process, as not all clusters of sparks evolve into Ca waves.
