For example, I have placed an electrode (circular pad or rectangular) in F3 over the scalp in EEG standard system. I want to find the area under the electrode over the gray matter both in MNI space and subject-specific space. Do you have any suggestions?</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Stay healthy,</div><div dir="ltr" data-setdir="false">Ghazaleh</div></div></body></html>
