Conventional functional magnetic resonance imaging (fMRI) is a blunt tool for studying the nervous system because it measures neural activity only indirectly, by way of hemodynamics and neurovascular coupling. Several alternative, nonhemodynamic functional imaging methods are now being explored.

Pharmacological Application of fMRI
2010Magnetic resonance imaging (MRI) allows the assessment of functional changes consequent to drug administration. Two main approaches have been used: changes in functional MRI signal following drug injection compared to the signal prior to injection and changes in task-related brain networks on drug compared to placebo.

Pediatric Applications of fMRI
2006Functional MRI has become an important pillar in the evaluation of children’s brain function. Its relevance in pediatric clinical and research is evident by the hundreds of articles published in peer-reviewed journals. We review the differences between fMRI in adults and children, with an emphasis on the technical challenges that the technique poses in

The combination of electroencephalography (EEG) with functional magnetic resonance imaging (fMRI) forms a powerful tool for the investigation of brain function, but concurrent implementation of EEG and fMRI poses many technical challenges. Here, the motivation for combining EEG and fMRI is explored and methods underlying the combination are described ...

Applications of fMRI to Psychiatry
2006The application of functional neuroimaging to characterize cortical dysfunction in patients with psychiatric disorders provides one of the most exciting in vivo techniques for the identification of both pathophysiologic factors and treatment effects.

In recent years, functional magnetic resonance imaging (fMRI) has become a widely used approach for neuroscience. However, this method has the potential to be improved with regard to both spatial and temporal resolution. The blood-oxygenation level-dependent contrast (BOLD) represents signal changes in T2 or T2* weighted images.
