The Wikipedia link for BigBrain you provided lists the resolution at 20 µm isotropic 3D voxels. That is ~2.71 µm in each direction.

  Nope. Yes, the Wikipedia link says 20 um isotropic resolution, but that means 20 um per direction. 20 um is a unit of length, while 20 um ^ 3, a unit of volume. If it were about volume, you'd be correct. Also, I just looked at the paper [1] and here it says: > To generate a data set with isotropic resolution, we down-scaled all images to 20 µm by 20 µm to match the section thickness of 20 µm. So that confirms the 20 um per direction, no? Edit: oh no, I just see that I wrote 1 um above, not 20. Not that 2.71 is correct but I guess that's what confused you. Corrected. Thanks!

    <slaps forehead> You are right about the resolution. Apparently I did not have my coffee because I work with voxels all the time.

      It's all good :)
