Dear Pari,
Could you define these as parametric regressors in your GLM? If so, you can select these in the normal way when you specify the DCM, and use them as modulatory inputs.
Best,
Peter

Hello SPM experts
I am working on somatosensory evoked potentials in order to investigate brain connectivity changes. I want to consider two basis functions such as: monotonic exponential decay and phasic function to have both rate (slow and fast) of connectivity changes (such as "Repetion suppression and plasticity in the human brain paper" ). How can I specify them in DCM scripts? is there any tutorial regarding this issue?
Thank you for any suggestion,
Best,
Pari
