The XPP code was run and set with MATLAB (using file runchange.m), using the MATLAB-XPP interface that can be downloaded here: http://www2.gsu.edu/~matrhc/XPP-Matlab.html There were five sets of simulations 1 The original Prescott model: prescott 2 Model with added T-current: prescott + T 3 Model with added T-current and adaptation current: prescott + T+adap 4 Model with added T-current and h-current: prescott + T+h 5 Model with added T-current with variable gT: prescott+Tvar All used the same input stimulus, taken from the experiments, stim.tab
