Just as humans are usually left- or right-handed, other species sometimes prefer one appendage, or eye, over the other.

A Bruker 9.4 Tesla preclinical animal MRI system will be sited at the Beckman Institute. The addition of the system to the institute’s Biomedical Imaging Center will aid in research in many areas, including brain development and function, and cellular mechanisms in cancer. The installation project will begin this fall and is expected to take a year.
