But what exactly does fMRI tell us? We know that its signals arise from changes in local haemodynamics that, in turn, result from alterations in neuronal activity, but exactly how neuronal activity, haemodynamics and fMRI signals are related is unclear. It has been assumed that the fMRI signal...

fMRI A special kind of MRI called a functional MRI (fMRI) maps brain activity. This test looks at blood flow in your brain to see which areas become active when you do certain tasks. An fMRI can detect brain problems, such as the effects of a stroke, Alzheimer’s, or abrain injury. ...
What exactly does an MRI show? It takes pictures of soft tissue (like organs and muscles) that you can't see on an X-ray. You can use it to see whether there are any tumors in your body or injuries to your bones. Why do you have to fast before an MRI with contrast? You may ...

Some studies found problems with EEG fMRI from inconclusive results. In some patients, no changes or insignificant changes in BOLD signals occurred when electrical activity increased. One study that mapped brain waves of epileptic patients over a long period of time in an attempt to identify regions...
The past five years have seen an outpouring of neuroimaging studies of memory — using both positron emission tomography (PET) and functional magnetic resonance imaging (fMRI). These studies have convincingly demonstrated that neuroimaging can be used to study the functional anatomy of normal human me...
Really all of these questions can be answered by surveying the scientific literature to see what's been learned about ASMR. Luckily, the body of work that exists does use the term ASMR, which makes it possible to do a literature search. This tells us two things: first, that nobody had ...
While this study provides an important initial foray into profiling the emotional difficulties of men with EDs, the DERS does not sufficiently distinguish between difficulties associated with early and late stages in the emotion cycle. Two of its subscales, ‘clarity’ and ‘emotional awareness’, ...
