Dear SPM user,Â
I am learning the DCM method mentioned in study ‘Dynamic causal modelling revisited, Friston et al., 2017’. >> This paper is one of the very nicely written paper I have ever read. It tells that why DCM 2003 is a good candidate for inversion of fMRI alone; at the same time it guide us about a mesoscale generative model of BOLD, that one would need for answering interesting questions about nature of fMRI and finally it address what needs to be done to achieve this goal : i.e. Bayesian fusion of multimodal DCM for fMRI and M/EEG. From method stand point, it nicely illustrate many key methods that were developed over years e.g., DCM, PEB, BMR, BMC to show how one could answer interesting question about neurovascualr coupling. I attached some of my slides which I hope answer your questions. 1.   In ‘priors on connectivity’ of ‘DEMO_dcm_fmri_nnm’ in the 1st study, what’s the two 3x3 matrices in DCM.a?
