[Freesurfer] Cortical Thickness under iEEG leads

2015-02-03 Thread rwlod...@uic.edu
Hello! I was just wondering what the best way to find the cortical thickness under specific intracranial EEG leads is. Is this even possible? I know freesurfer doesn't allow you to place leads onto the 3D model it generates, but if I knew exactly where the lead was is there some way to determine

Hello my names Rich. I am working on a project that involves creating 3D models of patient brains and placing ECoG (Electrocorticography) leads on these models. I have intra-operative pictures of the leads placed on the subjects and I'm using these pictures to attempt to accurately place the

? If you have that and a high-res T1, you can get very accurate reconstruction of electrode positions on the brain surface by corregistering the two. -zack On Wed, Oct 29, 2014 at 3:32 PM, rwlod...@uic.edu rwlod...@uic.edu wrote: Hello my names Rich. I am working on a project that involves
