About this Atlas: The brain is that of a 294-day-old C57BL/6J male with a body weight of 34.95 gm and a brain weight (fixed) of 476.1 mg. The animal's celloidin case ID number is 232 and you can view one of the slides used to make this atlas. Shrinkage during fixation and processing is 24% (linear). The in vivo grid compensates for this shrinkage. The abbreviations we have used to label the sections conform to those in the Franklin-Paxinos atlas (The Mouse Brain in Stereotaxic Coordinates, Academic Press, San Diego, 1998, ISBN Number 0-12-266070-6).
The brain and sections were all processed as described in our methods section. The enlarged images have a pixel count of 3055 x 2030 and the resolution is 4.5 microns/pixel for the processed sections.
Plans: In the next several years we hope to add several additional atlases of the same sort for
other strains of mice. This horizontal
C57BL/6J atlas and a DBA/2J coronal atlas were completed by Tony Capra, summer 2000, and additional atlases may
be made over the next several years. As describe in the MBL Procedures Section is not hard to make your own strain-specific atlas from the high resolution images in the MBL.
