Brains on a Chip
jhouserizer writes "The New Scientist magazine has an article reporting on new advances in keeping brain tissue alive (and working) on a "chip", with electrodes that can monitor the brain activity. Could this be a step toward computers that can learn as humans learn?"
Well this brain tissue will have to come from somewhere. If it comes from humans, we could have the same issues as with stem cell research. If it comes from animals (more likely) PETA will defecate copious amounts of brick
That's because it's not a breakthrough, it's commercialization of stuff that's been done in the academic labs for a couple years. Amazingly, it *does* take time to go from neat idea to marketable product. Electrode arrays can be a real bitch to fabricate.

Plus, as the other poster mentioned, Jerry Pine's work. However, AFAIK, Pine's no longer working on that project, having found other interests. Pity, because the neurowells (as noted by Peter Fromherz in the New Scientist article) give the kind of single-unit interface that might be very desirable. I know that my group is planning to use similar approaches.
