Dear all,I recently tried to model my fMRI data with non-linear DCM. But I do not know what do "States per region" and " Stochastic effects" mean and how to set it. I searched the spm8 manual, but did not get enough information. Could you please explain the basic ideas of these two terms? Thanks!Best regards,Hongbo--
