Short description

This a model from the article:
Complex bursting in pancreatic islets: a potential glycolytic mechanism.
Wierschem K, Bertram R. J Theor Biol 2004 Jun 21;228(4):513-21 15178199 ,
Abstract:
The electrical activity of insulin-secreting pancreatic islets of Langerhans is characterized by bursts of action potentials. Most often this bursting is periodic, but in some cases it is modulated by an underlying slower rhythm. We suggest that the modulatory rhythm for this complex bursting pattern is due to oscillations in glycolysis, while the bursting itself is generated by some other slow process. To demonstrate this hypothesis, we couple a minimal model of glycolytic oscillations to a minimal model for activity-dependent bursting in islets. We show that the combined model can reproduce several complex bursting patterns from mouse islets published in the literature, and we illustrate how these complex oscillations are produced through the use of a fast/slow analysis.

Curator's comment:

Figure 9 of the reference publication has been reproduced. Parameter values were obtained from table 1 and/or figure description. Initial conditions were obtained from steady state values (CellML) to speed up the simulation as the simulation requires a large time span (600,000 milliseconds). The simulation was performed in COPASI 4.22 (Build 170) and the figure was generated in MATLAB R2014b.
