By Thul R., Smith G. D., Coombes S.

We current a bidomain fire-diffuse-fire version that allows mathematical research of propagating waves of increased intracellular calcium () in residing cells. Modeling liberate as a threshold method permits the categorical building of touring wave suggestions to probe the dependence of wave velocity on physiologically very important parameters corresponding to the edge for unlock from the endoplasmic reticulum (ER) to the cytosol, the speed of resequestration from the cytosol to the ER, and the complete [] (cytosolic plus ER). apparently, linear balance research of the bidomain fire-diffuse-fire version predicts the onset of dynamic wave instabilities resulting in the emergence of waves that propagate in a back-and-forth demeanour. Numerical simulations are used to verify the presence of those so-called 'tango waves' and the dependence of wave velocity at the overall [].
