Telepathy exists! Scientists have connected the “minds” of two rats (VIDEO)
Researchers have succeeded in developing a rudimentary form of telepathy in animals, so that two rats they can send instructions only with the mind. Communication function even if some rats are far away from each other, on different continents.
Using microchips implanted in their brains, the rats were able to communicate with each other and work together to solve simple tasks, although in one experiment, they were thousands of miles away from each other.
The authors argue that this is the first experimental example of interface brain / brain, feeding hope that one day, animals, and people can read minds their peers.
Experiments were conducted by scientists at Duke University, USA, and, in their opinion, proves for the first time, that can be achieved exchange channel behavioral information directly from the brains of two animals, without resorting the usual forms of communication among animals.
Study leader Miguel Nicolelis, a pioneer in the study of brain interfaces / PC, says the study is the first step of many minds telepathic connection to form a “living computer” or “brain network” will allow the sharing of information within a group of animals.
“It is impossible to predict what new features would come out when the animals would interact as part of a network of brains,” said the researcher. “Theoretically, we could imagine that a combination of brains could develop individual solutions to a brain could not get one.”
HOW THEY DID IT:
Experimental results were presented in an article published in Scientific Reports, showing how microscopic electrodes implanted in rat brains allowed them to exchange the instructions, even if they were completely separate from each other.
The first rat, called “encoders” was taught to find water in its cage by pressing a lever when a light signal.
His brain was connected with that of another rat, called “decoder”, which is not illuminated signs. This animal second only to rely on instructions received via the mind, but it was stimulated properly, still managed to pull the right lever to reward in 70% of cases - far more than would have been likely statistically speaking, if acted randomly. This shows that he was mentally guided other rat, “encodorul”.
Remarkable is the fact that the communication seems to work both ways. Rat “encode” receive no reward (whether acted correctly) that rat “decoder” wrong act, as a result, “encodorul” became more determined and generated aa clearer brain signals to guide the decoder. Scientists have noted that when “decoder” wrong, “encodorul” present some changes in both brain function and behavior, partner to make it easier to understand what to do.
‘We detected cortical neurons that responded to both sets of whiskers‘.
Another test involved pairs of rats which had to distinguish one narrow opening wide using only “whiskers” (called scientific vibrissae, they are sensitive hairs, an important sense organ for rodents.) Again, to find that signals a rat helps the other to perform the correct action to obtain reward.
The results show that rat decoder begins to develop a kind of double identity, his brain integrates signals from two sets of vibrissae - his and his partner. The sensory cortex decoder tactile information begin to be represented not only from his own vibrissae, but also from those of rat encoders.
The experiment was repeated with another pair of rats, one of which was in Durham, USA, and another in Natal, Brazil.
