Brazil, Experiment | featured news

Two rats — one in North Carolina, the other in Brazil — worked together on a task by communicating telepathically, thanks to implants in their brain. Electrical signals from a "leader" rat’s brain were collected, encoded and then zapped into the "follower" rat’s cortex in the form of an electrical signal. The follower rat then pressed one of two levers based on a light visible only to the leader rat. The Duke University experiment is the first time two animals have collaborated through such an artificial link, and shows that the mammal brain can be trained to act on electrical signals from another animal.
