Rats do tasks while connected brain-to-brain

Signals transmitted from one animal to another seem to share information, but usefulness of findings questioned

The Vulcan mind meld is no longer the stuff of science fiction. Scientists have electronically linked the brains of pairs of rats, enabling one to apparently share information with the other. And unlike the Vulcan technique, there’s no need for close contact: Using an Internet connection, one rat in Brazil sent signals to the brain of a rat in North Carolina.

Similar experimental setups may help scientists probe how the brain’s circuitry incorporates information and perhaps even lead to som...
