Blind Rats 'See' Through Geomagnetic Brain Implants

"In an experiment that could significantly advance efforts toward providing a sensory input to blind people, scientists have shown that it is possible to enable blind rats to “see” by attaching tiny digital compasses to their brains. The findings of the study, published in the journal Current Biology, also open the doors to providing something akin to a sixth sense to sighted humans -- expanding their senses to detect even ultraviolet radiation and ultrasound waves."

The story is too old to be commented.
