location coordinates EXG channels

Hello Coen I have a question regarding ICA decomposition and the inclusion of EXG channels in EEGLAB. Am I right that for the inclusion of EXG channel in the ICA decomposition, I should specify the channel locations? Are there approximate lcoation coordinates available for the EXG channels, in my ca...

Re: Impact of reference electrode for import on data ?

Coen Thank you for your response. I had one extra question. With "non-biosemi" devices, a reference is chosen before eeg-recording. Then, it is usually advised not to choose an electrode that is an electrode of interest for your type of experiment, e.g., Cz in a language experiment. Do Biosemi-users...

Impact of reference electrode for import on data ?

When importing BDF file into EEGLAB, Biosemi users are prompted to select a reference electrode. Usually I use here a midline electrode (Cz or POz in my case). However, Cz and POz are also critical electrodes in the regions of interest in my experiments. My question is whether the choice of referenc...
