If a few very smart neuroscientists are right, with enough number crunching and a powerful brain scanner, science can pluck pictures—and maybe one day even thoughts— directly from your brain
For the past 10 years, Gallant has been running a neuroscience and psychology lab at Berkeley dedicated to brain imaging and vision research. He’s one of a few neuroscientists in the world on the verge of unlocking the key to mind reading through brain-pattern analysis using magnetic resonance scans and algorithms. By showing me a series of random photographs and evaluating fMRI readings from my primary visual cortex, Gallant says his technique can reconstruct imagery stored in my brain. His current method takes hours of analysis, but his objective is to hone the technology to the point where it can deduce what people are seeing in real time.
If successful, it could influence the way we do just about everything. Mind-reading machines could help doctors understand the inner worlds of people with hallucinations, cognitive disabilities, post-traumatic stress disorder and other impairments. Judges could use them to sneak a look into suspects’ brains by having them reenact the experience and reading their visions. Such machines could also determine whether someone using the insanity defense is faking it, or whether someone claiming self-defense truly feared for his life. On the flip side, the technology raises serious ethical concerns, with critics worrying that it could one day make our private thoughts vulnerable to snoops and hackers.
