Scientists are one step closer to knowing what you’ve seen by reading your mind.

Having modeled how images are represented in the brain, the researchers translated recorded patterns of neural activity into pictures of what test subjects had seen.

Though practical applications are decades away, the research could someday lead to dream-readers and thought-controlled computers.

“It’s what you would actually use if you were going to build a functional brain-reading device,” said Jack Gallant, a University of California, Berkeley neuroscientist.

The magnetic field in which I was immersed had a strength of three Teslas, so anything ferrous would have made itself evident quickly. That's 30,000 Gauss, for those used to the <a href="http://en.wikipedia.org/wiki/CGS" rel="nofollow">CGS system</a>. It is also 6.66% of the strength of the world's strongest non-pulsed magnet, located in Tallahasee, Florida. Ah, it's not every day a geek gets exposed to so much snazzy technology: cryogenics, superconductors, and all the signal processing and analysis stuff.
