On the basis of these findings, an alternative model to the passive diffusion of Ins(1,4,5)P 3 or Ca 2+ through gap junction channels is provided to explain the synchronization of Ca 2+ oscillation ... circuits of the current loop are presented in Doc. S2 of [5]. The fluctuation in the membrane potential of the Ca 2+ store may be due to the movement of Ca 2+ ions and the concomitant movement of other...
