Both groups were shown the same images of food while lying in an fmri scanner.
Can fmri predict when and if someone will regain consciousness after a traumatic brain injury?
What the fmri machine detects is the shifting proportions of oxygenated blood in any given region of the brain.
Until the advent of fmri, the options for studying living human brains in such ways were severely constrained.
As it is improved and expanded, fmri research may one day reveal an equally astonishing view.
The fmri scan measures blood flow in the brain, and can sense when certain areas are activated.
The fmri has done away with the need for cracked-open skulls.
During an fmri study, a subject lies down in the middle of a giant magnetic tube.
And then you put them in a fmri machine and the size of amygdalae actually shrinks, and there is tons of research like that.
An fmri, on the other hand, requires no radioactive compounds.
Abbreviation for functional magnetic resonance imaging. In FMRI, a patient is placed in a high magnetic field and delicate measurements of magnetic fields associated with processes like blood flow are made. In this way, the functioning of organs like the brain can be monitored as they occur. (Compare MRI.)
Note: FMRI images are used to determined which parts of the brain “light up” when a function such as speech or recognition is performed.
