Sprague-Dawley Rat Brain (Waxholm-80um)

The Rat (Waxholm-80um) atlas is based on the brain of a 397.6 g male Sprague-Dawley rat. The brain was imaged with MR ex vivo, resulting in T2-weighted gradient echo images with 40 um isotropic spatial resolution. 76 brain structures were segmented [1, 2].

E. A. Papp prepared a version suitable for PMOD and made it available for download on nitrc.org: https://www.nitrc.org/projects/whs-sd-atlas/

An adapted version of this atlas is distributed with PMOD as a convenience to our users. Because the original 40um isotropic resolution is beyond typical in vivo MR and far beyond the resolution applicable for PET image analysis, it was down-sampled to 80um. The original text file associated with the atlas was re-organized to consecutively number the regions. Note: down-sampling left no actual voxels in regions 6,33,47,49,60,63 as numbered in the atlas text file.
