fMRI or functional magnetic resonance imaging, is a relatively young brain activity imaging technology. It works based on detection of the dynamic regulation of blood flow in the brain. Medically, this is termed the haemodynamic response, however it is simply tracking brain activity based on increasing and decreasing demand for oxygen and glucose in the haemoglobin of the blood in the brain.

Doubts have been raised, over the accuracy of many fMRI (functional magnetic resonance imaging) studies, used to decode the information in the brain.
fMRI or functional magnetic resonance imaging, is one of the newest brain imaging technologies for the first decade of the 21st century. It is a basic form of Brain-Computer Interaction.
A 10 year old girl from Germany is the subject of a great deal of medical scrutiny of late. She has occasional spasms, and can only see in one eye. Other than that she seemed perfectly normal, until fMRI was used to image her brain.
Part of a talk from TED 2008, this podcast by Christopher deCharms takes a look at what, for VR is a low-hanging holy grail for neurology: A way to use fMRI to show brain activity -- thoughts, emotions, pain -- while it is happening.
The debut of a new type of magnetic resonance sensor for brainwaves and electrical activity - which changes the game totally for both fMRI and MEG. For the first time ever, portable, low-cost versions of both are actually a possibility.

Technology Review's long, and in depth look at the rise of diffusion spectrum imaging, and how this new neural interface imaging technique is rapidly accelerating the study of both human and animal brains to an extent unparalleled by any previous imaging technique, even fMRI.
Diffusion spectrum imaging is a new technique at time of writing, which allows magnetic resonance brain imaging, at a much higher level of fidelity than fMRI permits.
