Athymic Nude Rat Brain Atlas will provide the first stereotaxic brain atlas of the athymic nude rat (Crl:NIH-Foxn1rnu), a T-cell deficient rat model commonly used in experimental studies and pre-clinical safety and efficacy studies. This 2D vector-based atlas contains coronal, sagittal, and horizontal brain sections of an athymic rat brain rendered from a single cleared specimen, placed in a computerized 3D environment. The maps enable readers to better calculate co-ordinates to target specific structures for toxin, virus, or cell delivery using stereotaxic surgery. This atlas will be a valuable resource for any neuroscientist who wishes to work with nude rats in experimental and pre-clinical studies.
