Recent developments in magnetic resonance imaging (MRI) now make it possible to study
human brain function non-invasively. The method is called functional MRI (fMRI) and relies
on changes in the MR signal produced by increased oxygenation of blood in active regions
of the brain. Images of brain activation are obtained by comparing the MR signals before
and during a task. This makes it possible to localize which areas of the brain are
involved in performing a particular task or function. Cooperation with the Radiology
department on campus makes it possible to use their two MR scanners outside of clinic
hours. Current projects in my lab are focused on motor control and acute pain. This
research is highly nterdisciplinary and is part of a developing research group in
cognitive neuroscience which plans to use fMRI in the study of visual and language
processes, among other interests. This group, in turn, is part of a larger cognitive
science program being established on campus.
