So, if you choose N ICA components, is each of them fit separately ? in other words, for source localization, does the EEGLAB algorithm consider all the selected components at a same time and do localization for all of them – if the presence of one component affects of the location of the dipole which corresponds to the other component- ? if yes, so, how can we say one dipole is associated with one ICA component?<o:p></o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span style='mso-list:Ignore'>2-<span style='font:7.0pt "Times New Roman"'> </span></span><![endif]><span dir=LTR></span> Is there any study on the fact that how many dipoles should be chosen from N-Channel EEG/MEG recording?<o:p></o:p></p><p class=MsoNormal>Best,<o:p></o:p></p><p class=MsoNormal>Iman<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif"'>Iman M.Rezazadeh, PhD<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif"'>Postdoctoral Research Fellow<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif"'>Center for Mind and Brain<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif"'>University of California, Davis<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif"'><a href="mailto:irezazadeh@ucdavis.edu">irezazadeh@ucdavis.edu</a><o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif"'>Cell:310-490-1808<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif"'>Skype: Imanmr<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
