What FUNCTIONAL MAGNETIC RESONANCE IMAGING (FMRI) means: An MRI-based technique for measuring brain activity. It works by detecting the changes in blood oxygenation and flow that occur in response to neural activity – when a brain area is more active it consumes more oxygen and to meet this increased demand blood flow increases to the active area. fMRI can be used to produce activation maps showing which parts of the brain are involved in a particular mental process.
- Definition Fluorophore:
- Dictionary chemical compound that can re-emit light upon light excitation. Fluorophores are usually bonded to a molecule serving as a marker to stain tissues, cells, or materials in methods including functional magnetic resonance imaging (fmri).
- Definition Fluorescence:
- Dictionary The emission of light by a substance that has absorbed light or other electromagnetic radiation. The absorbed and emitted light are usually different wavelengths and therefore produce different colors functional magnetic resonance imaging (fmri).
