Moving to using ion-specific additional currents. David Nickerson 2007-05-23 Adding in an additional calcium SR flux for use in extending the model. David Nickerson 2007-06-22 A component which sums the provided potassium fluxes. A component which sums the provided sodium fluxes. A component which sums the provided calcium membrane fluxes. Gives the rate of change of intracellular concentration due to sarcolemmal calcium fluxes. A component which sums the provided calcium fluxes. Gives the rate of change of intracellular concentration due to SR calcium fluxes. An additional calcium flux which can be used by higher level components to modify or extend the base TNNP Ca fluxes into and/or out of the SR. $\mathrm{Ca\_SR\_flux}=\mathrm{Jleak}+\mathrm{Jrel}+\mathrm{JCaSR\_additional}-\mathrm{Jup}$
