Hi Katharina

they are pretty similar but you can imagine some things affecting one and not the other (e.g. white matter atrophy might shrink the white surface area more than the pial). Or conditions like polymicrogyria might affect the pial more than the white

Dear administrators, I've got the problem that I cannot make out the difference between "area" and "area.pial". As far as I understand "area" refers to white matter surface area while "area.pial" includes everything up to pia mater (including CSF). Unfortunately I don't know what I am exactly looking at when I run the "area.pial"-simulation. What does it tell me?

Thanks a lot,

Katharina
