<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">I am using the mutual information analysis from the IBTB toolbox as incorporated in fieldtrip to run connectivity analysis on resting state EEG data (32 channels) of participants exposed to narcotic
gases. I found an increase in mutual information in the frontal region compared to baseline. I am interested to further localize this effect, so I setup a LCMV beamformer source localization. However, in the derived time series of the virtual channels the
mutual information effect is completely gone. Could someone help me explain this effect? Could it be that LCMV, in its attempt to calculate the spatial filters, cancels out the mutual information in the EEG signals?<o:p></o:p></span></p>
