London: Venturing into the preserve of science fiction and stage magicians, scientists in the United States on Wednesday said they had made extraordinary progress towards reading brain.

The researchers said they had been able to decode signals in a keypad of a brain to identify images seen by a volunteer, according to their study, published by the British journal Nature. The tool used by the University of California at Berkeley neuroscientists is functional magnetic resonance imaging (fMRI), a non-invasive scanner that 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.
