Frieldtrip question, but I am hoping you can answer it anyways. I am trying to
design an eeg experiment with hydrocephalus patients. However, most will have
multiple shunts. I realise this will likely have dramatic effects to the activation
patterns. A quick Google search gave me some rather old papers. I am
wondering what is the best way to compare their activity to controls?
Also, I will have access to their MRIs. Can I use beamforming? <span style="font-size:12pt" class="">Unfortunately, I don't have
access to an MEG.</span></p><div style="margin: 0cm 0cm 12pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span class=""></span><br class="webkit-block-placeholder"></div><p class="MsoNormal" style="margin:0cm 0cm 12pt;font-size:12pt;font-family:"Times New Roman",serif">Thanks in advance for any
