"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."

(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. [more inside]

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.
