Hi, David, few notes (questions): 1) could you send me the data file? 2) do you use absolute or relative power for Newroguide? The relative should work perfectly? 3) the data you record by Mitsar do not depend on parameters of registration. They include the whole frequency band. 4) there is a group (10-20%) of ADHD children with beta excess. Keep me updated. Juri VD> Hello, VD> we have recently run a couple of children with ADHD using the Mitsar and VD> seem to find excess in beta as opposed to the more expected slow theta VD> activity. I have attached a file and would welcome any comments any may VD> have. VD> Also, the montage we used had a baseline of 0, a low cut of 0.1, high cut of VD> 50 and notch of 50(0.1)Hz. Could this in some way have influenced the EEG in VD> any way?? VD> thanks VD> david
