Hi Jed,

if too much of the brain is missing it will violate many of our basic assumptions. How big a resection do you mean? And exactly what goes wrong?

cheers, Bruce

Hello!

I've been using Freesurfer to build maps of the cortical surfaces of surgical epilepsy patients who have volunteered to participate as research subjects. It works great, except when these patients have had previous resections. In these cases, recon-all fails; I know there are ways that people get around this when working with brains that have lesions (manually filling in white matter, e.g.) but is it possible to get a reconstruction of the brain as it actually is? For example, in the case of someone who has previously had an anterior temporal lobectomy, I would love to end up with a model that does not have an anterior temporal lobe.

I'm sorry if this is an obvious question - I've been digging through the archives of this list and furiously Googling and I've only found descriptions of how to manually fill in holes (due to lesions or caused by bad segmentations) in intact brains.

Thanks in advance for any pointers, Jed _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
