Calcium ions play an important role in human and animal life on subcellular, cellular, and multicellular levels. They are responsible for muscle contraction, involved in secretory function and moderate many different processes in the brain. In this study it is shown how the intracellular calcium and intracellular calcium store take part in generation of different types activities in neural ensembles: synchronous bursting, chaotic bursting, chaotic spiking, and wave propagation. It is demonstrated how external spatiotemporal noise can produce synchronous calcium oscillations and local travelling calcium waves in a randomly coupled ensemble of neurons. © 2000 American Institute of Physics.

    Connexin36 (Cx36) plays an important role in insulin secretion by controlling the intercellular synchronization of Ca2+ transients induced during stimulation. The lack of drugs acting on Cx36 channels is a major limitation in further unraveling the molecular mechanism underlying this effect. To...
