<div dir="ltr">Dear List,<div><br></div><div>I'm working on a frequency analysis of resting EEG with relatively few channels (6 scalp, 2 mastoids, 2 EOGs), and I'd like to be able to extract reliable estimates of low frequency power. In previous analyses I have used ICA to remove artifacts, but this was with 64-channel data. Has anyone used ICA for artifact removal with a low-density channel array, or could anyone recommend resources on pipelines for this type of data and analysis?</div><div><br></div><div>If ICA can't be used with this data, then I suppose the alternative is to remove segments containing artifacts, and then only analyse the remaining segments that are long enough to extract an estimate of the lowest frequency (e.g. ~1.5 seconds for a minimum frequency of 2 Hz). Is this correct, or is there a better approach?</div><div><br></div><div>Sorry that this is not strictly an EEGLAB question. I am doing the analysis in EEGLAB so any EEGLAB-specific tips would be appreciated!</div><div><br></div><div>Thanks,</div><div>Becky<br clear="all"><div><div dir="ltr"><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">______________________________</span><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">______________</span><br style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)"><br style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)"><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">Becky Gilbert (nee Prince)</span><br style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)"><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">PhD Researcher</span><div><br></div><div><a href="http://www.york.ac.uk/psychology/staff/postgrads/becky.gilbert/" target="_blank">http://www.york.ac.uk/psychology/staff/postgrads/becky.gilbert/</a><br></div><div>Lab C120<br><div><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">Department of Psychology</span><br style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)"><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">University of York</span><div><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">Heslington, York, YO10 5DD, UK</span><br></div></div></div></div></div>
