The application of functional magnetic resonance imaging to neuropharmacology.
The technique of functional magnetic resonance imaging (fMRI) has the capacity to acquire data with spatial and temporal resolution that far exceeds other currently available methods of non-invasive investigation of brain function. This coupled with its ability for serial studies makes it an attractive prospect for investigating the effects of pharmacological agents in the brain. Recent advances in fMRI have been made in the areas of reward and dependence, brain trauma and injury, psychotropic drugs and pain using small animals. Although the use of fMRI in pharmacological studies is becoming popular, there are various associated complications, such as the possible interference of drugs with the mechanisms that give rise to the pharmacological fMRI signal, and local or global cardiovascular changes that might produce functional responses unrelated to neural activity. Consideration of these concerns, coupled with careful attention to experimental detail and verification procedures, promises to make pharmacological fMRI use a valuable tool for understanding the actions of drugs in the brain.
