Model simulation of the SPOC wave in a bundle of striated myofibrils

SPOC (SPontaneous Oscillatory Contraction) is a phenomenon observed in striated muscle under the intermediate activation conditions. To understand the SPOC properties in a bundle of myofibrils, we have extended the single myofibril model to a two-dimensional (2D) and a three-dimensional (3D) model, in which myofibrils are elastically connected side-by-side through cross-linkers between the Z-lines and the M-lines. These models could reproduce various patterns of SPOC waves experimentally observed in a bundle of myofibrils by choosing appropriate values of elastic constants of the cross-linkers and external spring.
