Hi,
I am looking for a way of figuring out the orientation vector of the neurons within a voxel. That is, in which direction is the dipole of the neurons pointing at. This could be possible to calculate if there is a way of determining the position of the inner and outer layer for each voxel, which I am assuming is something Freesurfer does when it calculates gray matter thickness. If you could direct me to some relevant literature or an online tutorial I would be extremely grateful.
best regards Daniel
