abbr.
functional magnetic resonance imaging

FMRI

abbreviation for
(Pathology) functional magnetic resonance imaging: a technique that directly measures the blood flow in the brain, thereby providing information on brain activity
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.fMRI - a form of magnetic resonance imaging of the brain that registers blood flow to functioning areas of the brain
magnetic resonance imaging, MRI - the use of nuclear magnetic resonance of protons to produce proton density images
BOLD FMRI - functional magnetic resonance imaging that relies on intrinsic changes in hemoglobin oxygenation

If further research proves successful, Saxe predicts that fMRI scans of brain entropy could one day help in assessing problems in brain function in people with depression, post-traumatic stress disorder, or autism, in which processing information becomes difficult.
proposed a statistical method, named as Hierarchical Exponentially Weighted Moving Average (HEWMA), on fMRI data to detect the state change of BOLD signals in response to stimulus [21].
To test the new approach, researchers from King's College London and the University of Manchester, gave 64 patients, who were in remission from major depressive disorder and not on prescribed medication, fMRI scans to look for atypical connections in the brain.
This article reviews fMRI evidence that, compared with non--substance-abusing control subjects (NSACs), brain executive control networks are weakened or "tuned down" and appetitive drive networks are strengthened or "tuned up" in active alcoholism.
These regions are analogous to brain locales in humans that respond to human voices, the team found by playing the same recording for 22 people undergoing fMRI scans.
It is generally agreed that while fMRI identifies cortical regions involved in language, ECS identifies those critical to the function.
1million project, funded by the Wellcome Trust, will develop new and sensitive statistical methods to combine information from fMRI studies.
The basis of fMRI is that deoxygenated blood is magnetic whereas oxygenated blood is not.
In addition, the fMRI study suggested that Lyrica reduced visual activation or sensory stimulation that activates pain and affects related brain regions in fibromyalgia patients.
A second group underwent nonguided fMRI aimed at the left temporoparietal cortex, and the third group had a placebo TMS coil placed perpendicular to the head.
