In a stunning first for neuroscience , research worker have created an electronic link between the brains of two rats , and demonstrated that sign from the mind of one can help the second figure out basic mystifier in real time — even when those animals are split by grand of miles .
Here ’s how it works . An “ encoder ” git in Natal , Brazil , cultivate in a specific behavioural labor , adjure a lever tumbler in its John Milton Cage Jr. it knows will earn it a reward . A brain implant records action from the rat ’s motor lens cortex and converts it into an electric sign that is delivered via neural inter-group communication to the brain implant of a second “ decoder ” git .
Still with us ? This is where thing get interesting . Rat number two is in an entirely dissimilar cage . In fact , it ’s in North Carolina . The second rat ’s motor cerebral mantle processes the signaling from rat routine one and — despite being unfamiliar with the behavioral job the first rat has been conditioned to perform — uses that entropy to press the same lever .
The experiment , the final result of which are published gratuitous of commission in today ’s upshot ofScientific Reports , was led by Duke neuroscientist Miguel Nicolelis , a pioneer in the theatre of Einstein - machine interfaces ( BMIs ) . Back in 2011 , Nicolelis and his colleagues unveiled the first such user interface capable ofa bi - directing link between a brain and a virtual eubstance , allowing a monkey to not only mentally see to it a false arm , but receive and sue receptive feedback about tactile property like grain . in the beginning this month , his team unveiled a BMI thatenables rat to find unremarkably invisible infrared light lightvia their sense of touch .

But an intercontinental thinker - meld represents something new : a brain - to - head interface between two alive scum bag — one that enable realtime sharing of sensorimotor information . It ’s a scientific first , and while it ’s not telepathy , per se , it ’s certainly something skinny . Neither git was necessarily aware of the other ’s existence , for representative , but it ’s decipherable that their minds were , in fact , communicating . “ It ’s not the Borg,”Nicolelis tells Nature ’s Ed Yong . What he has created , he says , is “ a raw primal neural system made of two psyche . ”
Said skittish system is far from perfect . Untrained decoder rats receiving input from a trained encoder partner only chose the correct lever around two - thirds of the time . That ’s definitely upright than random odds , but still a far cry from the 95 % accuracy of the encoder rats .
What this two - brain system does do , Nicolelis argue , is turn on the rats to function with one another in unprecedented ways . And while nervous communication between two animals on only separate continents is impressive in its own right * , Nicolelis says the most groundbreaking app of this technology — a 3- , 4- , or n - intellect “ encephalon net ” — is still to come .
“ These experiments establish the power to launch a sophisticated , direct communicating linkage between puke brains , ” he read in a statement , “ so basically , we are creating an constituent computer that figure out a puzzle . ”
“ We can not betoken what sort of emergent properties would appear when animals begin interact as part of a brain - net , ” he continues . “ In theory , you could think that a combination of brains could provide result that individual brain can not achieve by themselves . ”
