Scientists are taking one step closer to reading your mind using brain
Imagine tapping into the mind of a coma patient, or watching one’s
own dream on YouTube. With a cutting-edge blend of brain imaging and
computer simulation, scientists at the University of California, Berkeley,
are bringing these futuristic scenarios within reach.
Using functional Magnetic Resonance Imaging (fMRI) and computational
models, UC Berkeley researchers have succeeded in decoding and reconstructing
people’s dynamic visual experiences – in this case, watching
Hollywood movie trailers.
As yet, the technology can only reconstruct movie clips people
have already viewed. However, the breakthrough paves the way for reproducing
the movies inside our heads that no one else sees, such as dreams and
memories, according to researchers.
“This is a major leap toward reconstructing internal imagery,”
said Professor Jack Gallant, a UC Berkeley neuroscientist and coauthor
of the study published online today (Sept. 22) in the journal Current
Biology. “We are opening a window into the movies in our minds.”
