[Eeglablist] Cortical Area Calculation

[Tarik S Bel-Bahar]

Hello Ibtissem, some notes below.


*************************************************************************

see multiple published articles that specify direct relations between
specific channel sets and cortical regions, usually in the context of
TMS.
See the below for example:

Automated cortical projection of EEG sensors: Anatomical correlation
...  L Koessler - ‎2009

You can also google search and "google scholar" search on a topic as follows:
 converting 10-20 electrode position to MNI (or Talairach)  coordinates
or converting 10-10 electrode position to MNI (or Talairach) coordinates
and you should be able to find some other resources.

It seems one can also do this automatically in Brainstorm, google the
page  below for more info.

Converting 10-20 System locations to (average) MNI template ...
