<p class="MsoNormal"><span lang="EN-US">Dear EEGlab expert users,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I am interested in studying corticomuscular coherence. I have identified sources, through DIPFIT, those that the variance is smaller than 15%. Thereafter, I made sure these sources represent brain activity. Here is my
question: should I project back all the sources (variance smaller than 15% and brain activity) regardless of their locations or it is a good idea to project back, in sensor-space, only the sources that are in the sensorimotor cortex? Thereafter, I intend to
calculate corticomuscular coherence selecting sensors over the right or left sensorimotor cortex.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Another possibility would be to calculate corticomuscular coherence between sources located in the sensorimotor cortex and muscle activity. Thus, there is no need to project back the sources in the sensor-space.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Nonetheless, I have not seen papers calculating corticomuscular coherence between sources and muscle activity. I wonder why, I have probably overlooked the literature unless there are reasons not to use sources to calculate
corticomuscular coherence.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Any suggestion would be appreciated,<o:p></o:p></span></p>
