Researchers Give Lab Rats A ‘Sixth Sense’

In the near future, people could be augmented with the ability to feel magnetic fields, radio waves, or infrared light, reports the BBC:

US researchers have effectively given laboratory rats a “sixth sense” using an implant in their brains. An experimental device allowed the rats to “touch” infrared light – which is normally invisible to them.

The team at Duke University fitted the rats with an infrared detector wired up to microscopic electrodes that were implanted in the part of their brains that processes tactile information.

Lead author Miguel Nicolelis said this was the first time a brain-machine interface has augmented a sense in adult animals. The experiment also shows that a new sensory input can be interpreted by a region of the brain that normally does something else.

“We could [make the rats] sensitive to any physical energy,” said Prof. Nicolelis. “It could be magnetic fields, radio waves, or ultrasound.

“I see,” said the blind man, with the bionic eye. For centuries the hearing impaired have used devices to aid their hearing, but it is only till now that we may be able to help the blind see again. Bangkok Post reports:

For a man whose view of the world has slowly faded to black over 30 years, a device that allows him to see flashes of light has kindled his hope of one day gazing upon his grandson’s face.

A career electrician who grew up in Greece and came to the United States as a young man, Elias Konstantopoulos first noticed his vision getting poorer when at age 43 he absentmindedly tried on a relative’s eyeglasses and found he could see more clearly with them than without.

Soon after, he visited a doctor who tested his sight and discovered he was no longer able to see his outstretched arms from the corners of his eyes.
