UC Berkeley researchers used brain scans of the visual cortex and computational models to reconstruct what the individual is seeing. From UC Berkeley:
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."
BB pal Jim Leftwich points out that the reconstructed video looks strikingly similar to how images from a science fiction "dream recorder" were represented in Wim Wenders' captivating 1991 film Until The End Of the World. Here's a frame grab Jim made from his VHS tape of the movie.
