Hello everybody,
when I tried to understand the neural dynamics of DCM I coded in Matlab a user interface that allows you to change the model parameters and to see how they affect the hemodynamic and neural signal. Maybe this program is also interesting for others here who would like to understand how the neural model of DCM looks like under noise-free conditions. You can download the files here:

The program uses some functions of SPM 8. You need an early version of SPM 8 as the internal structure of the DCM variables have changed recently.
Best,
Martin
