Recently, someone pointed me toward this news report, which I have cross referenced (only to find that everyone got their information from the same limited source). Isolated rat brain learns to control flight simulator through BCI. As I understand it, rat neurons formed an interactive network with an electrode in complete isolation. (The brain mass was kept alive in a solution.) The electrode was connected to a flight simulator, and over some time, the "brain" learned to keep the plane flying straing n' steady. This raises (many) questions. Because the neural matter had no knowledge of an objective, in contrast to most Brain-Computer Interface demonstrations, where the subject is actively trying to accomplish some given task, how was this goal accomplished? Put another way: What was it about the straight, level path of the simulated jet that made it a favorable condition? Why wouldn't the rat brain keep conditions constant but less pleasing to the scientists involved, like a continual barrel role? Was the electrode possibly wired in such a way that signals were only relayed when the jet was off balance, and the brain naturally seeks out the "path of least resistance", so to speak - resistance referring to interference, in this case. Perhaps the mechanisms that govern the equilibrium in mammals could offer some insight. What do we know about this system? I will continue to read, and will update if I come across anything relevant.
