[Eeglablist] Electrode placement and ICA

[busey at indiana.edu]

I'm setting up a new 32 channel system and I need to decide on electrode 
location placements. I do mainly visual components at around 100-300 ms that 
tend to be distributed near the back of the head. Does the ICA procedure 
benefit from equally-spaced electrodes over the entire head, or is it better to 
cluster them in the region of interest? If I do this, I will have unequal 
spacing, since I will have some frontal electrodes. Is there something magic 
about equidistant electrode placement for ICA?


Thanks,
