What a news: Neural 'extension cord' developed for brain implants:
A "data cable" made from stretched nerve cells could someday help connect computers to the human nervous system. The modified cells should form better connections with human tissue than the metal electrodes currently used for purposes such as remotely controlling prosthetics. (...) Tests have already shown that electrical signals can be transmitted in both directions along the cord. (...) Christopher James, who works on brain-computer interfaces at Southampton University, UK, gives the work a cautious welcome. "This approach does sound like a good idea," he says. "Although directly attaching electrodes to the brain has been shown to work, the long term effects are not known".
Why do I blog this? I find intriguing the emphasis on invasive brain-computer interfaces. Though it's often not necessary (EEG could be another solution as mentionned in the article), there seems to be a conspicuous fascination towards plugging stuff into one's body.
