EEG and MEG Data Analysis in SPM8

Figure 12

Examples from results display of DCM-ERP. The EEG data was taken from the mismatch negativity experiment available from the SPM website (a) “ERPs (mode)” display for the first two (out of eight) modes. The thin lines show the data and the thick lines the model prediction. Response to frequently presented tone is shown in blue and response to rare tone—in red. (b) “ERPs (sources)” display showing the predicted dynamics of two of the sources in the model (left and right auditory cortices). Each source consists of 3 neuronal populations. Response to frequently presented tone is shown in blue and response to rare tone—in red. (c) “Coupling (B)” display showing the posterior means for the gain modulations of the connections. (d) Posterior probability map from the same display showing for each modulated connection the probability that the effect of experimental conditions (frequent versus rare) on the connection was different from zero.
