3D DTI anatomical rat brain atlases have been created by the UNC- Chapel Hill Department of Psychiatry and the CAMID research collaboration. There are three age groups, postnatal day 5, postnatal day 14, and postnatal day 72.
The subjects were Sprague-Dawley rats that were controls in a study on cocaine abuse and development. The P5 and P14 templates were made from scans of twenty rats each (ten female, ten male); the P72, from six females. The individual cases have been resampled to isotropic resolution, manually skull-stripped, and deformably registered via an unbiased atlas building method to create a template for each age group. Each template was then manually segmented using itk-SNAP software.
Each atlas is made up of 3 files, a template image, a segmentation, and a label file. This work was funded by the UNC Neurodevelopment Disorders Research Center HD 03110, the NIH STTR grant R41 NS059095, and the NIH Program Project IP01DA022446-02.
