For those of you interested in learning more about brain imaging technologies and what they can and can not tell researchers I recommend the following resource written by Carolyn Asbury, a Dana Foundation grants consultant. The brief primer covers several imaging techniques and what each reveals. The creation of this primer was developed with the assistance of James P. Basilion, Ph.D., Assistant Professor, Center for Molecular Imaging Research, Massachusetts General Hospital.

From Dana.Org: This primer is intended to help readers gain a better understanding of how the brain and immune system function normally, and how their functions are altered by diseases.
