Brain signals are being tamed for various things, and while they are being used to detect lies, scientists seem to have cracked another nut on the same line. Scientists have developed a mind-reading machine, which decodes and converts brain signals into moving images seen on a computer screen. The machine can produce pictures of what a person is seeing and what he remembers from an incident or the like.
Professor Jack Gallant, during research carried out at the University of California, Berkeley, used a functional magnetic resonance imaging (fMRI) scanner to scan brain activity of two volunteers watching a video and used the results to recreate crude images of what they were seeing. Results were then fed into a specially designed computer which searched to the links between configuration of colors, shapes and movements along with the patterns of activity in the brain. The findings are yet to be revealed but it is said to be close to the mark.
