Example: Running the model in opencor after changing the ending point to 60 seconds and creating (+) three graphs and then adding plots to each graph by right-clicking the wi.wi, wi.wi', and model_parameters.Ko (selecting Plot against integration variable for each) creates the following graphs qualitatively similar to those in Fig 5A:
