[Eeglablist] ICA ADJUST

[Tarik S Bel-Bahar]

Hello Alexandre,

Spatial ica regularly and easily detects eye artifact ICs, with or without
EOG channels. Thats because eye artifact patterns are picked up at frontal
electrodes.

My recommendation is to try your ocular Ic detection in several ways. With
32 channels you should easily be able to capture ocular ICs as well some
other classes of artifact ICs.

Do note that some ica classification algorithms request eog electrodes, or
channels that can be treated as if they were eye channels.

Dear all,

I'm interested in ICA process to deal with ocular artifacts in an ERP
study.
However I have some doubt about the best electrodes montage : when using a
32 channels montage, is this necessary to set EOG electrodes (we previously
used this approach by derivating some electrodes) or ICA
detection/rejection algorithms (eg ADJUST) can deal without EOG electrodes?

Regards,

Alexandre
