Local gyrification index

Post by ChristianeJ. »

Dear experts,

I would like to calculate a gyrification index. However, instead of calculating this over the whole brain I would like to calculate this for only a part of the brain:So is it possible to calculate a gyrification index for lets say the Prefrontal cortex only?

Thank you in advance

Kind regards
Christiane

Hi,
Currently the Morphologist toolbox doesn't provide lobes definitions and boundaries, so it forbids to easily define lobar gyrification indices.
It may be done when we have such a lobar parcellation. We may rely on the upcoming brain mesh parameterization in the cortical surface toolbox (in the current state it is not stable enough) - a new version of the toolbox should be available in june I guess.
