Telepathic control of another person’s body is a small step closer. By linking the technologies of two brain/computer interfaces, human volunteers were able to trigger movement in a rat’s tail using their minds.
Recently, researchers linked the brains of two rats so that they worked together to accomplish a task. Such techniques are unlikely to be applied to humans any time soon because they require invasive surgery to implant electrodes into the brain.
Now Seung-Schik Yoo of Harvard Medical School in Boston and colleagues have created a system that connects a human to a rat via a computer, without the need for the human or the rat to have brain implants.
The human volunteers wore electrode caps that monitored their brain activity using electroencephalography (EEG). Meanwhile, an anaesthetised rat was hooked up to a device that made the creature’s neurons fire whenever it delivered an ultrasonic pulse to the rat’s motor cortex.
When monitoring the human’s brain activity, the researchers looked for a specific EEG pattern known to correspond to visual stimulation. As the volunteers watched a strobe light blinking on a computer screen, the EEG wave synchronised to match the frequency of the strobe (see the "SSVEP" line on video, above).
But when they switched to concentrating on moving the rat’s tail, the change in their focus disrupted the EEG, triggering a signal to be sent to the computer. The computer translated this signal into an ultrasonic pulse, which stimulated the rat’s motor cortex, causing its tail to move. Using this system, all six of the volunteers were able to trigger movement in the rat’s tail with little difficulty.
Yoo says it should be possible for two humans to use a similar system in the foreseeable future. Such a system could, for instance, be used to help a paralysed person relearn to use their limbs by having their therapist initially move them with their mind.
But Ricardo Chavarriaga at the Swiss Federal Institute of Technology (EPFL) in Lausanne and others say that while the experiment is an interesting application of the two technologies, linking them together does not reveal much about the ability to link two brains.
Because the rat was anaesthetised to isolate the effect of the intervention, he says it is not clear that the experiment realistically models what would happen if a conscious brain was stimulated this way.

Meet AISight – The Artificial Intelligence Software Being Installed on CCTV Networks Globally 2014 04 24 If you thought that CCTV cameras tracking your every move in public was bad enough, you’re going to just love AISight (pronounced “eyesight” of course). The invention of a Houston, Texas based company called BRS Labs (which stands for Behavioral Recognition Systems) is headed by former secret service special agent John Frazzini, and this Orwellian surveillance platform brings artificial intelligence ...
Biofuel Made From Corn Waste Less ‘Green’ Than Gasoline 2014 04 24 Biofuel created from corn waste may not be the clean, eco-friendly oil alternative the United States government is hoping for. A new study has found that fuel generated from harvested corn leftovers creates more greenhouse gases than conventional gasoline — at least in the short term.
The fuel under study, called cellulosic ethanol, has been touted in recent years as a ...
Swedes open coffin of 850-year-old king 2014 04 24
Scientists pried open the 850-year-old casket of King Erik the Holy on Wednesday, hoping to find out more about the king, his crown, and his eating habits.
"This was a very special occasion, especially considering the importance of Saint Erik religiously in Sweden," Uppsala Cathedral Chaplain Lars Åstrand told The Local.
The casket contained the bones of King ...
John Kerry and the Pope set to face off with Jewish Knight Templars on the Temple Mount 2014 04 24
This is the week that supposedly spells the end of the peace process or its end. My money is on a continuation that has no real substance or direction.
What’s the alternative?
With Passover and Easter over, Secretary Kerry can return to the Middle East crisis. This, after dealing so successfully with crisis in the Ukraine. [Is the author joking? - RIC]
