<p class="MsoNormal">Dear EEGLAB list,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">While reading through papers for my experiments, I just became curious (with some confusion) on the dipole fitting approach of the ERP data(for a specific task).
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">According to my understanding the ERP wave consists of several components such as P1,N1, P2 , N2 and P3 mainly (stimulus dependent). As I am intending to use ICA based source localization(using DIPFIT plugin) I wanted to find out on what
degree the two dipole fitting approaches are differing in BESA and DIPFIT with ICA.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoListParagraph" style="margin-left:20.25pt;text-indent:-18.0pt;mso-list:l0 level1 lfo1">
<![if !supportLists]><span style="mso-list:Ignore">1.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Am I correct if I say that with BESA, dipoles can be fitted to individual components of the ERP waveform?
<o:p></o:p></p>
<p class="MsoListParagraph" style="margin-left:20.25pt;text-indent:-18.0pt;mso-list:l0 level1 lfo1">
<![if !supportLists]><span style="mso-list:Ignore">2.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Do independent components for cognitive activity in brain represents ERP components(P1,N1, etc)?
<o:p></o:p></p>
<p class="MsoListParagraph" style="margin-left:20.25pt;text-indent:-18.0pt;mso-list:l0 level1 lfo1">
<![if !supportLists]><span style="mso-list:Ignore">3.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Since I have minimal(correct to say no..) experience in ERP, how do I know my dipole localisations with ICA are correct? For instance, in a visual task I would expect to see one or more dipoles in visual area, but when changing the conditions
such as colour or shape where else do I get dipoles? Or simply, how do I have a hypothesis for the ICA component related dipoles?<o:p></o:p></p>
<p class="MsoListParagraph" style="margin-left:20.25pt;text-indent:-18.0pt;mso-list:l0 level1 lfo1">
<![if !supportLists]><span style="mso-list:Ignore">4.<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>With very limited neuroscience knowledge how do I get around with localisations to extract a task related neuronal activity?

<p class="MsoNormal" style="margin-left:2.25pt">Sorry about throwing a lot of questions at the list, but I have always found EEGLAB list as very friendly and a very expertized group. So, your advice will be highly appreciated to move forward in my work.<o:p></o:p></p>
