<font face="Calibri">Dear all,<br>
<br>
I am doing my PhD in Visual Neuroscience and quite recently
started my EEG analysis with EEGLAB.<br>
In my experiment two stimuli are presented bilaterally with one of
them changing it's color. I am trying to create ERPs contra- and
ipsilateral to the color change, but not sure how to proceed in
EEGLAB.<br>
<br>
There is only one message in the discussion list with the idea of
"Swap the data, not the channels. Leave the channels alone." <br>
But how does it work? <br>
- contralateral: data of left-hemispheric electrodes for changes
on the right side and data of right-hemispheric electrodes for
changes on the left side<br>
- ipsilateral: data of left-hemispheric electrodes for changes on
the left side and data of right hemispheric electrodes for changes
on the right side<br>
<br>
It would be wonderful to get some help with that!<br>
<br>
Kind regards from Bremen,<br>
Dani<br>
