The long distance link was successfully done between a rat at Duke and a rat at the University of Natal in Brazil. Prof. Nicolelis believes that if he can do this long distance link successfully, he can one day be able to link millions of rats together to solve the same simple problem. Prof. Christopher James of the University of Warwick says that the only way the signals can be sent is a implants on the brain, not just on the top of the head.
Although the topic is quite intriguing and really amazing, it seems wrong to cut open anyone, human or rat's, head to insert a chip so they can communicate with another brain. Since, I believe this, I am biased against the idea so I tried to understand it at all angles. There are many ethical problems that come up with this topic though. One is the fact that you must cut open the scalp to insert the implant. This is a very invasive way of reaching the brain. I don't like the idea of this at all. One thing I see that is great about brain communication is the fact that people or animals would be capable of sharing sensory and motor skills. Another thing that could come good out of it is that if one person does not have enough of something in their body, someone could send them a signal telling them to make what they need, say a particular type of cell. All in all, I found this article to very intriguing and I think it will be interesting to see where this goes in the near future, since there are many pros and cons.
