Excerpt
Functional magnetic resonance imaging (fMRI), a noninvasive method for mapping human brain function, was developed 15 years ago. This technique, based on the blood oxygen level dependent (BOLD) contrast, is sensitive to the localized hemodynamic changes that occur with increased neural activity. Over the first decade following this discovery, fMRI was used extensively to map brain activity evoked from sensory, motor, cognitive, and emotional tasks in healthy individuals. More recently, this technique has been applied to further our understanding of neurobehavioral disorders, such as Alzheimer’s disease, epilepsy, brain tumors, stroke, traumatic brain injury, and multiple sclerosis. …
