Electrodiffusion dynamics in the cardiomyocyte dyad at nano-scale resolution using the Poisson-Nernst-Planck (PNP) equations
Fig 19
Illustration of two ODE model representations of the dyad dynamics.
The ionic concentrations are assumed to be constant (in space) in each considered compartment. A: The ODE model consists of one dyad compartment, , and one larger compartment representing the surrounding cytosol,
. B: The ODE model consists of two dyad compartments (one near the Ca2+ channel,
, and one near the RyR,
), in addition to the larger compartment representing the surrounding cytosol,
.
