If I need to rebuild a wall in my house why should I tear down and rebuild all the other good parts? In analogy, why change (by multiplying reconstructing) eeg segments when there are no blinks, tremor, muscle or pletysmo in those segments.

The problem with 19 ch is that we can stumble over the overcomplete situation (more sources then sensors) and that artefact and genuine brain activity is lumped together. Removing IC components that also index for brain slow wave activity from frontal regions can be problematic in case of frontal tumor (glioma). Missing them is one of my many (clinical fears and concerns). <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:14.0pt;color:#1F497D;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:14.0pt;color:#1F497D;mso-fareast-language:EN-US'>Sincerely<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:14.0pt;color:#1F497D;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:14.0pt;color:#1F497D;mso-fareast-language:EN-US'>PS I do not think that you have to explain ICA nor other signal analysis algorithms to Dr Thacher. </span><span lang=EN-US style='font-size:14.0pt;font-family:"Segoe UI Emoji",sans-serif;color:#1F497D;mso-fareast-language:EN-US'>😊</span><span lang=EN-US style='font-size:14.0pt;color:#1F497D;mso-fareast-language:EN-US'> but feel free to do so if that is your ambition.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:14.0pt;color:#1F497D;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:14.0pt;color:#1F497D;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='color:#1F497D;mso-fareast-language:EN-US'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'> Jason Palmer [<a href="mailto:japalmer29@gmail.com">mailto:japalmer29@gmail.com</a>] <br><b>Sent:</b> Sunday, June 18, 2017 9:53 PM<br><b>To:</b> 'Robert Thatcher' <</span><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><a href="mailto:rwthatcher2@yahoo.com"><span lang=EN-US>rwthatcher2@yahoo.com</span></a></span><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'>><br><b>Cc:</b> 'Iman Mohammad-Rezazadeh' <</span><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><a href="mailto:irezazadeh@ucdavis.edu"><span lang=EN-US>irezazadeh@ucdavis.edu</span></a></span><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'>>; 'Ramesh Srinivasan' <</span><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><a href="mailto:r.srinivasan@uci.edu"><span lang=EN-US>r.srinivasan@uci.edu</span></a></span><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'>>; 'Stefan Debener' <</span><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><a href="mailto:stefan.debener@uni-oldenburg.de"><span lang=EN-US>stefan.debener@uni-oldenburg.de</span></a></span><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'>>; 'Arnaud Delorme' <</span><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><a href="mailto:arno@ucsd.edu"><span lang=EN-US>arno@ucsd.edu</span></a></span><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'>>; 'eeglablist' <</span><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><a href="mailto:eeglablist@sccn.ucsd.edu"><span lang=EN-US>eeglablist@sccn.ucsd.edu</span></a></span><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'>>; </span><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><a href="mailto:pnunez@tulane.edu"><span lang=EN-US>pnunez@tulane.edu</span></a></span><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'>; 'Georges Otte' <</span><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><a href="mailto:georges.otte@telenet.be"><span lang=EN-US>georges.otte@telenet.be</span></a></span><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'>><br><b>Subject:</b> RE: [Eeglablist] ICA Misinformation<o:p></o:p></span></p></div></div><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:black'>Dear Robert,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:black'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:black'>Thank you for your reply and data. I think it would be very helpful if you could explain how the data you are presenting is used by clinicians and why it causes them great concern. I do not find it surprising at all that measures are significantly changed when eye-blinks are removed. When you say “artfact free data” you are not referring to selected time periods without eye-blinks are you? If you are comparing periods containing eye-blinks to data reconstructed with eye-blinks removed, then clearly the measures will be different. The simple fact that measures are different is not surprising. As far as I am able to interpret the figures, the significant difference is largely over the frontal electrodes, where eye-blinks are influential. Again, that is entirely what one would expect. If removing eye-blinks from data did NOT cause any change in measures, then THAT would be surprising and seem to argue that removing eye-blinks is unnecessary at all.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:black'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:black'>Again, I would very much appreciate reference to some clinically relevant application beyond stating a simple difference in many measures. For example, if there were a study of beta activity in orbito-frontal cortex, and clinicians were finding a significant difference in populations at the channel level, perhaps using a more traditional eye-blink removal technique, but not using the ICA based eye-blink removal, then I think that would be very compelling.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:black'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:black'>Also, are you claiming that eye-blinks should not be removed by any method?

I believe Arnaud has admirably refuted your alpha example and I have not seen any convincing evidence that there is a clinically significant alteration caused by judicious use of ICA for artifact removal and data reconstruction. Your claim that ICA reconstruction is decoupled from the brain, etc., is incorrect. The back-projection of the source data, after components like eye-blinks are removed, is entirely "coupled" to the brain and the original data recording. The reconstruction / back-projection is NOT based on z-score ICA component activations, but on the simply linearly transform based activations. It is simply not true that the ICA reconstructed data is divorced from the brain. The same phase and amplitude relationships and generating source locations will exist in the reconstructed channel data without artifacts like eye-blinks, line-noise, scalp muscles, etc. as exist in the original channel data.<o:p></o:p></span></p></div></div><div><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Helvetica Neue";color:#26282A'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Helvetica Neue";color:#26282A'>The notion that it is wrong to use ICA for eye-blink removal because "every data point is changed" again does not sound like a reasonable statement. It is equally correct to say that the EM potential added to the EEG by eye-blinks themselves "change the data". There are several papers that demonstrate the superiority of ICA based eye-blink removal over the "many other methods" that exist, and thus it is incorrect to say that there is no justification to use ICA over other methods. If you turned your polemic against other methods of eye-blink removal, such as regression, I have no doubt that you would find similar or greater grounds for objection based on you stated reasons.<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Helvetica Neue";color:#26282A'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Helvetica Neue";color:#26282A'>I have not used or heard of WinEEG.

Your extreme warnings about the "phase distortion" caused by ICA do not seem to be founded in a correct understanding of the way ICA works. It is a linear transformation, creating a simple linear decomposition of the signal into constituent components, including eye-blinks. Theorems from differential geometry are irrelevant. Reconstructing the data with the eye-blink component left out will NOT cause any phase distortion in ICA. The statement that "every data point is changed" is not scientifically compelling. ICA is INCREDIBLY USEFUL FOR ARTIFACT REJECTION AND DATA RECONSTRUCTION as demonstrated by countless published papers.

The <a href="http://yahoo.com" target="_blank">yahoo.com</a> email you are using is consistently being put in "spam" by gmail, and not even showing up in my Microsoft Outlook mail (even in junk mail). Gmail claims that the address "fails <a href="http://yahoo.com" target="_blank">yahoo.com</a>'s required tests for authentication". It would be very helpful and appreciated for this discussion, assuming there is no ready solution to the <a href="http://yahoo.com" target="_blank">yahoo.com</a> issue, if you might consider using an alternative email.<o:p></o:p></span></p></div></div></div></div></div></div></div></div></body></html>
