A<unk>  is a direct communication pathway between the<unk>  of one animal and the<unk>  of another animal.<unk>  to<unk><unk> s have been used to help rats collaborate with each other. When a second rat was unable to choose the correct lever, the first rat noticed (not getting a second reward), and produced a round of task-related neuron firing that made the second rat more likely to choose the correct lever. In 2013, Rajesh Rao was able to use electrical<unk>  recordings and a form of magnetic stimulation to send a<unk>  signal to Andrea Stocco on the other side of the University of Washington campus. In 2015, researchers linked up multiple<unk> s, of both monkeys and rats, to form an “organic computer. It is hypothesized that by using<unk> -to-brain<unk> s (BTBIs) a biological computer, or<unk> -net, could be constructed using animal<unk> s as its computational units. Initial exploratory work demonstrated collaboration between rats in distant cages linked by signals from cortical microelectrode arrays implanted in their<unk> s. The rats were rewarded when actions were performed by the "decoding rat" which conformed to incoming signals and when signals were transmitted by the "encoding rat" which resulted in the desired action. In the initial experiment the rewarded action was pushing a lever in the remote location corresponding to the position of a lever near a lighted LED at the home location. About a month was required for the rats to acclimate themselves to incoming<unk> waves." Lastly, it is important to stress that the topology of BTBI does not need to be restricted to one encoder and one decoder subjects. Instead, we have already proposed that, in theory, channel accuracy can be increased if instead of a dyad a whole grid of multiple reciprocally interconnected<unk> s are employed. Such a computing structure could define the first example of an organic computer capable of solving heuristic problems that would be deemed non-computable by a general Turing-machine. Future works will elucidate in detail the characteristics of this multi-brain system, its computational capabilities, and how it compares to other non-Turing computational architectures Miguel Nicolelis of Duke University, one of the investigators who did the experiment with rats, has done previous work using a<unk><unk> computer<unk> .
