Dipole simulation and reconstruction with Rössler oscillations as source activation with a variable number of (left), (center) trials (right).

<p>The data is simulated with additive uncorrelated sensor noise of 20% RMS and brain noise generated by uncorrelated, randomly located and orientated dipoles in the grey matter. <b>A</b> Connectivity of the connected Rössler oscillators indexed with and , cf. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0044633#pone-0044633-t001" target="_blank">Table 1</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0044633#pone-0044633-t002" target="_blank">2</a>. <b>B</b> Connectivity of the reconstructed source activation with a conventional LCMV beamforming approach. <b>C</b> Reconstructed connectivity by applying a WMA filter to reduce thermal noise captured by the MEG device on sensor data (WMA+LCMV). All patterns in b) and c) are processed by removing exponentially decaying correlations as described in the Results (Pattern de-correlation).
