“Sixth Sense” Is Promised to Be Given via Brain Implant

sixth sense implantantLab rats gained a “sixth sense” via brain implant that allowed them to “touch” the infrared light, according to data published in the journal Nature Communications.

Seeing in the infrared spectrum

Team of researchers at Duke University in North Carolina, led by Dr. Miguel Nicolelis, announced during the annual conference of the American Association for the Advancement of Science in Boston that this new breakthrough opens the way for a new generation of prosthetic devices that are controlled by the brain and in the future will probably give people the ability to “see” in the infrared spectrum of electromagnetic radiation.

Laboratory rats were implanted with infrared sensors, connected through tiny electrodes with the part of their brain responsible for processing tactile information. Thus, when the animals accepted infrared signals, the brain interpreted them as tactile stimuli.

The pseudo-touch

Within one month, the rats had learned to fully correlate the signals of infrared light received by the brain, with a pseudo-tactile sensation, without involving the skin in the process.

That is, while the animals saw infrared light, they perceived it as a touch stimulus and scratched their fur, feeling like touching the invisible infrared light.

This new sensory ability reminds the rare phenomenon of ‘synaesthesia’, i.e. the ability of some people to perceive a sensory stimulus with a different sensation (eg “see” music or “smell” colors).

Vision through … touch

sixth sense ratAs explained by Dr. Nicolelis, these experiments – which were successfully repeated on monkeys – showed that a sensory stimulus (infrared vision) can be processed in an area of ​​the brain that has evolved for a different sense (touch) without side effects, since the normal tactile perception of the animals was not disrupted by the implant.

This, according to the scientists, means that theoretically in the future blind people with damaged visual cortex would be able to see again with the help of an “electronic eye”, which would receive optical signals and process them in other brain region.

Dr. Nicolelis said: “what we did shows that the adult brain can acquire new abilities never experienced before.” As he added, except for the infrared light, a similar “synesthesia” could possibly occur with ultrasound, radio waves, magnetic fields etc.

Enhancement of the sensory capabilities

Thus, the appropriate electronic implants could dramatically expand the sensory capabilities of the human brain, with the result that people would be able to perceive things that are not endowed by biological evolution with appropriate sensors.

In the same vein, Dr. Nicolelis said that the research team achieved the first “brain-to-brain interface”, passing for the first time direct brain signals from one animal to another.

Brain-to-brain interface

As he said, “it is an interface that no one had ever dreamed that would be possible.”

The international scientific community awaits with interest the publication in the scientific journal Nature next month. It is most likely to open the way for electronic implants which one day will allow direct communication between the brains of people.

    Sorry, but your article is about nothing of “know how”. Infrared measuring way was described in many places, related to “Symbio Telepathy” in Internet 3 years ago even.

      it’s ok, but according to this logic most articles and websites do not offer nothing new, since in general terms they describe the same things :mrgreen:
