Star rats

Researchers at a university in the United States have done an experiment that sounds as if it is out of a sci-fi movie. They’ve taken two rats, one in Brazil and the other in the United States, and connected their brains so that the rats can share some information. First, the two rats were trained to press a lever when a light is turned on. Electrodes were connected to each rat’s brain. One of the rats was shown the light signals and it opened the right levers. This rat’s brain activity was captured electronically and sent over the Internet to the other rat’s brain. After receiving the rat’s electronic brain signals, the other rat opened the right lever most of the time (7 out of 10 times) without receiving any light signals. Some scientists are praising this work, while others say that 7 out of 10 times isn’t good enough.
