Figure 8. Schematic diagram of the Inline graphic model.

Figure 8

Inline graphic represents cytoplasmic Inline graphic concentration, excluding a small local Inline graphic (whose concentration is denoted by Inline graphic) close to the Inline graphic release site (i.e., an Inline graphic cluster). Upon coordinated openings of the Inline graphic, SR Inline graphic (Inline graphic) is first released into the local domain (Inline graphic) to cause a rapid increase in Inline graphic. High local Inline graphic then diffuses to the rest of the cytoplasm (Inline graphic), and is eventually pumped back to the SR (Inline graphic).
