Scientists say they have made extraordinary progress towards reading the brain, venturing into the preserve of science fiction and stage magicians. The researchers say have decoded signals in a key part of the brain to identify images seen by a volunteer, according to their study, published today in the journal Nature. The tool used by the University of California at Berkeley neuroscientists is functional magnetic resonance imaging (fMRI). This non-invasive scanning detects minute flows of blood within the brain, thus highlighting which cerebral areas are triggered by light, sound and touch. Their zone of interest was the visual cortex, a frontal part of the brain that reconstitutes images sent by the retina. Article
