Using the parameters described under the figures in the paper usually does not result in plots that look like the published figures. Here is an example for Figure 1C:
Published figure 1C:

Using the parameters described in the paper for the figure:

Searching parameters and looking for a best fit results in the following:

To get the best fit (see XPP folder _bestFit), a DC current was added (not described in paper), Vt parameter was changed (also not described for the figure), and a different input current was used than the one described.
Similar issues with the other figures in the paper.
