From Wired:Brain Scan Technology

This article peaked my interest because I use a (obviously) very advanced method of this in my story Siege Therapy.

From the article:

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.

From Siege Therapy:

“This is not a mind reading machine, Doctor Planck.  This machine gives us the data we need to extrapolate how his mind works.  We have spent weeks reading his patterns while controlling his stimuli.  We show him a dog and record the pattern.  We show him fire and record the pattern.  After all of these baseline recordings are gathered we can see patterns to his, well, patterns.”
