Calcium (Ca(2+)) oscillations are ubiquitous signals present in all cells that provide efficient means to transmit intracellular biological information. Either spontaneously or upon receptor ligand binding, the otherwise stable cytosolic Ca(2+) concentration starts to oscillate. The resulting specific oscillatory pattern
