Our work uses short-lived (i.e., 2-110 minute half-life) cyclotron-produced, positron-emitting radionuclides with positron emission tomography (PET) and functional Magnetic Resonance Imaging (f MRI) for the in vivo study of the central nervous system of humans and non-human primates.

The research can be divided into two general categories: methods development and applications. In the area of methods development, we are concerned with the development and testing of mathematical models of blood flow, metabolism and pharmacology in in vivo systems. This work has ranged from strategies for the measurement of blood flow, blood volume, oxygen consumption, tissue pH and glucose utilization to receptor pharmacology. Most recently, we have been involved in investigations of image analysis strategies, including image averaging techniques, response localization in functional images and statistical analysis techniques. Applications involve studies in normal subjects using PET and fMRI to determine systems within the normal human brain concerned with specific cognitive and emotional functions. We are studying patients with psychiatric diseases such as depression and anxiety to determine the systems (language, memory, attention) responsible for the disease and the response of these systems to treatment.
