My colleagues, E. A. Stein and A. S. Greene, both physiologists, direct this latter half. These experiments are carried out both at 1.5 and 3T in order to assess the magnetic field dependence of contrast. In another study, my student B. Biswal and I have studied fluctuations that are superimposed on fMRI signals. These fluctuations resemble noise, but are physiological in origin. Bands at the cardiac and respiratory rates have been identified along with low-frequency fluctuations that appear to be neuronal in origin.
Current research involves the effect of hypercapnia on physiological fluctuations.
Peter A. Bandettini, PhD , Adjunct Assistant Professor, Biophysics. I received my BS in Physics from Marquette University in 1989, and my PhD MRI of Human Brain Activation Using Endogenous Susceptibility Contrast from the Medical College of Wisconsin in 1994. I was a postdoctoral fellow at Massachusetts General Hospital and Harvard Medical School from 1994 to 1996. My research interests include most aspects of functional MRI using endogenous contrast.
