The file 'BRAAAAAAIN! 3D Printer Model' is (stl) file type, size is 1.7MB.
I know you want to print a brain of your very own. Observe this lovely normal brain. I downloaded the raw mri files from http://bit.ly/7d9TFA and converted them in http://www.3d-doctor.com/
3dDoctor can output some pretty messy STL's so you'll probably want to fix them up in NetFabb or another mesh repair tool.
