The atlas was constructed from the average of eight individual co-registered MR image volumes of C57BL/6J mouse brain collected at postnatal day 0. The atlas space defined by multi animals captured the average geometry of native anatomical space for normal mouse brains at P0, avoiding possible anatomical outliers present in one animal. The label volume based on this average brain is consisted of 13 anatomic structures, which provides a template to facilitate feature-based registration. The probability maps for individual anatomical volumes were defined by the eight -registered MR images used to construct the atlas, which serve as references to map the atlas onto test images and to label the regions of interest of test images. The probability map with a restrictive threshold provides a more accurate mapping, while that with lower threshold labels an image more completely.
The atlas is comprised of:
There are a number of different applications that can be used to view the atlas. Here is a list of a few of them:
