<div class=Section1>
<p class=MsoNormal>I have a 20 minute dataset of UP/DOWN/LEFT/RIGHT finger
movements from 144 channel biosemi system. We recorded the movements using 128
channels EEG , 2 wrist which picked up ECG and 4 EOGchannels, the rest
unconnected.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have selected a montage of 43 electrodes across C3 C4 and symmetry
of head line. I ve noticed peaks and troughs alternating at different frequencies
at different movements. I run ICA on up epochs and down epochs and it gives me
43 components for each. Can someone tell me is each component mach relating to
the actual channel number as in is ICA removing the noise from each channels
contribution to the overall signal matrix. As in if I llok at component 37 or
C3 in my plot , is that the filtered C3 main component with neighbouring
electrode noise filtered out.<o:p></o:p></p>
