Functional magnetic resonance imaging
fMRI has become one of the most important imaging techniques for assessing
cognitive function in a broad rangeof applications. Most of the work outlined
here was performed by collaborators at the University of Illinois. Currently
Penn State University has two 3 tesla machines available for fMRI studies at
Hershey Medical School, and is planning to acquire a system on main campus by
the end of 2007.
