Photographs of sufficient magnification are included to permit investigators to judge for themselves the veracity of the atlas delineations.

Anatomy of rat brain. Access online via elsevier 2006. The laboratory rat was developed from the norwegian rat rattus norvegicus by an american physiologist henry donaldson who started a breeding colony in 1906 at the wistar institute in philadelphia. The specimen is an 80 day old male sprague dawley rat.

Paxinos george and charles watsonthe rat brain in stereotaxic coordinates. In addition an intracranial rat brain mask was formed from this canonical brain by assigning 1 for intracranial voxels and 0 for others as shown in figure 1b. The waxholm rat atlas is an open access volumetric atlas of the sprague dawley rat brain.

The rat atlas is a three dimensional 3d computerized map of rat brain anatomy created with digital imaging techniques. The is based on high resolution isotropic ex vivo t2 weighted mri and dti data acquired at the duke center for in vivo microscopy at resolutions of 39 μm and 78 μm respectively. Three principal strains are now commonly used for scientific study.

Developed at the wistar institute. The rat brain is analyzed through stereotaxic localization of discrete brain areas and the subdivisions of many areas of rat brain are mapped using plates and diagrams. Medulla with spinal cord.

Thus after normalizing an individual image to the rat brain template the intracranial tissues could be conveniently extracted. Electronic sharing and interactive use are benefits afforded by a digital format but the foremost advantage of this 3d map is its whole brain integrated representation of rat in situ neuroanatomy.
