, 2006 This review concentrates on functional MRI (fMRI) methods to identify the epileptic focus; i.e., ictal and interictal fMRI. First, established clinical applications of fMRI in the field of epilepsy are briefly introduced: fMRI of sensorimotor, language, and memory functions can be considered already as clinically relevant tools to identify eloquent ...

The field of pain research has progressed immensely due to the advancement of brain imaging techniques. The initial goal of this research was to expand our understanding of the cerebral mechanisms underlying the perception of pain; more recently the research objectives have shifted toward chronic pain – understanding its origins, developing methods for

Recent brain imaging work has expanded our understanding of the mechanisms of perceptual, cognitive, and motor functions in human subjects, but research into the cerebral control of emotional and motivational function is at a much earlier stage. Important concepts and theories of emotion are briefly introduced, as are research designs and multimodal ...

Simultaneous EEG and fMRI Recordings (EEG-fMRI)
2013Scalp EEG is characterised by a limited spatial resolution and by a low sensitivity to generators distant from the cortical surface. In contrast, fMRI is characterised by a good spatial resolution and it is sensitive to signal of deep brain structures. By combining EEG with fMRI, it is possible to detect blood oxygenation level-dependent (BOLD) signal ...

Localization of eloquent areas is of utmost importance in neurosurgical planning, especially in epilepsy surgery. Mass, destructive, or developmental lesions may distort brain anatomy. Functional MRI (fMRI) can localize eloquent areas despite these distortions and provide useful information for the planning of tailored resections. This paper deals with

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.

Trends in Neurosciences, 2007
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.

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 ...

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.
