Functional MR imaging.
Functional MR (fMR) imaging offers unprecedented spatial and temporal resolution of brain cognition. The impact of this technology on neuroscience research is just now being explored. This article discusses blood oxygenation level-dependent-based fMR imaging. Topics include the origin of the MR-based signal, data acquisition and sequence dependence, and paradigm design issues--issues that need to be fully understood to properly design and interpret the fMR imaging experiment.
