<div dir="ltr">Dear Raquel,<div><br></div><div>I suggest you use AFp9 and AFp10 EEG channels. For VEOG, you need to make up dedicated channel locations. I thought I've seen VEOG channels in the EEGLAB's available channel list i.e., just enter SVEOG and IVEOG (or something like that; these list could be seen in head model setting GUI) and 'look up locs' and their default locations are automatically retrieved. Actually, I think I've seen it in this list recently.</div><div><br></div><div>Makoto</div><div><br></div><div>Makoto</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Jul 25, 2016 at 5:54 AM, Raquel London <span dir="ltr"><<a href="mailto:raquel@dragondelapatagonia.com" target="_blank">raquel@dragondelapatagonia.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Dear EEG labbers,<div><br></div><div>I am struggling with the channel locations.
