Hello Brainstorm experts

I am attempting source reconstruction with EEG data. I am in the stage to compute the head model right now.when I compute the head model, the bem contains three layers (scalp skull brain ),)I want to know (1)whether the brain and cortex_15002 are the same layer？
(2)how many cortical layers between the dipole source and the scalp electrodes？

Thanks!

hello Francois ：
Thank you for your reply！
I want to know why generate BEM surfaces have the outer skull and inner skull ?

Because these are the layers needed for the BEM computation.
