Fig. 5.

a). This panel shows the time-dependent changes in (log scaling of) the intrinsic and extrinsic connections as a function of window number. The posterior expectations correspond to the coloured lines (blue and cyan correspond to intrinsic connectivity, while green and red lines report the forward and backward connectivity respectively). The true values are shown as broken lines, the posterior estimates as full lines and the 90% confidence intervals as grey areas. b) Predicted (solid lines) and observed (dotted lines) cross spectra for pre-ictal (blue) and ictal (red) periods. This example uses average spectra from the first seizure to illustrate the quality of the model fit and the spectral data features that inform the posterior estimates of the model parameters. The absolute values of the (complex) cross spectra are shown in the upper right panel.
