Results obtained with 10,000 particles and discrepancy 1. (a) Dynamical model selection function. (b) Superposition of all estimated dipoles at all time points. (c) Clustered dipoles and corresponding waveforms. (d) Average dipoles of the clusters in (c). Estimated dipoles show an expected spread around the true sources (cf Figure 3). From (b), it is evident that Sources 1 and 6, that is, the ones producing the weakest field, are not recovered. The model selection function indicates neural activity beginning at 10 ms (when the maximum probability switches from the zero-dipole model to the one-dipole model) and lasting until about 145 ms; in two time windows (30–55 ms and 105–130 ms), a two-dipole model is selected.
