Pharmacological magnetic resonance imaging: a new application for functional MRI.
Various methods, including functional magnetic resonance imaging (fMRI), have recently been developed to allow investigators to study functional activity in the living brain. Such techniques are now being used to investigate regionally specific brain activity associated with the administration of CNS-active drugs. fMRI in particular is increasingly recognized as being a relatively non-invasive way to perform pharmacological investigations in experimental animals, healthy human volunteers, and individuals with CNS disease. This use of fMRI, dubbed 'pharmacological MRI' or 'phMRI', holds the promise of providing relatively straightforward pharmacodynamic assays and can be used to establish brain-penetrability parameters, or dose-ranging information for novel therapeutic compounds.
