Scientists wired two ratsbrains together and the result was mutual problem solving: “We created a new central nervous system made of two brains.”

“The brains of two rats on different continents have been made to act
in tandem. When the first, in Brazil, uses its whiskers to choose
between two stimuli, an implant records its brain activity and signals
to a similar device in the brain of a rat in the United States. The US
rat then usually makes the same choice on the same task.
Miguel Nicolelis, a neuroscientist at Duke University in
Durham, North Carolina, says that this system allows one rat to use the
senses of another, incorporating information from its far-away partner
into its own representation of the world. “It’s not telepathy. It’s not
the Borg,” he says. “But we created a new central nervous system made of
two brains.”

Nicolelis says that the work, published today in Scientific Reports1,
is the first step towards constructing an organic computer that uses
networks of linked animal brains to solve tasks. But other scientists
who work on neural implants are sceptical. Lee Miller, a physiologist at
Northwestern University in Evanston, Illinois, says that Nicolelis’s
team has made many important contributions to neural interfaces, but the
current paper could be mistaken for a “poor Hollywood science-fiction
script”. He adds, “It is not clear to what end the effort is really
being made.”
