"Adrian Owen still gets animated when he talks about patient 23. The patient was only 24 years old when his life was devastated by a car accident. Alive but unresponsive, he had been languishing in what neurologists refer to as a vegetative state for five years, when Owen, a neuro-scientist then at the University of Cambridge, UK, and his colleagues at the University of Liège in Belgium, put him into a functional magnetic resonance imaging (fMRI) machine and started asking him questions. Incredibly, he provided answers."

How the Brain Reveals Why We Buy. "Most of us know that branding palpably influences our choices and shopping habits, but researchers suspect that branding can also fundamentally change the way we comprehend sense impressions.
At least that is the obvious conclusion to be drawn from the only (so far) classic study in neuromarketing, a fascinating study of what can be called the Pepsi paradox. "

Functional MRI (fMRI) is a widely used technique of brain imaging in the cognitive sciences, allowing researchers to visualize what part of the brain is responding to certain stimuli, resulting in
striking images of
live brains. These days, fMRI is seeing more non-research use, such as forming the basis of controversial
new lie detectors. Craig Bennett, a postdoctoral researcher at UCSB,
submitted a whole Atlantic salmon to fMRI analysis, and found that this fish could apparently detect, and respond to, the the emotional state of human beings (
poster). Remarkable science, especially considering the salmon was dead at the time.

Win a free MRI machine: An odd medical equipment distribution scheme, winanmri.com will give away a free MAGNETOM to the hospital that gets the most votes for their submitted video. (videos on right hand side).

Don't Even Think About Lying fMRI is poised to transform the security industry, the judicial system, and our fundamental notions of privacy. I'm in a lab at Columbia University, where scientists are using the technology to analyze the cognitive differences between truth and lies. By mapping the neural circuits behind deception, researchers are turning fMRI into a new kind of lie detector that's more probing and accurate than the polygraph, the standard lie-detection tool employed by law enforcement and intelligence agencies for nearly a century.

Sucked in! MRI scanners are hungry for any metal objects in the nearby vicinity, with hilarious and
sometimes tragic results.
The roughly 10,000 scanners in the United States are found not just in hospitals, but in storefront clinics and even mounted on trucks, making rounds of small hospitals or parking at malls to do scans for a fee.

Safety of MRI scans - annoying and temporary free registration required.If movement whilst being scanned may not be safe, then what about the heart, lungs, blood and even a foetus? You can't keep those still.
