Rat brain image database

We are gathering T2-weigthed images of rats(Wistar strain) by using a high-resolution 7T-MRI which is designed for small animals. From these image data, we are constructing the average brain atlas of rats.

By matching an individual rat's brain image with this atlas, we can identify small areas of the brain precisely.


Wistar Rat MRI Atlas

Data sets of Wistar rat MRI template, atlas, probabilistic masks and MATLAB toolkits are available for research use.
