Abstract

For a variety of purposes we have begun implementation of a PET method for studying dopamine release. We used the dopamine D2-type receptor antagonist [11C]raclopride to study dopamine function in the rhesus monkey brain in response to an amphetamine challenge. [11C]raclopride is susceptible to competition from endogenous dopamine, whereby dopamine released into extracellular space reduces the number of binding sites available for the tracer.
