The researchers have already shown that the stretch-grown axons can be implanted into rat spinal cord and continue to grow. Since feeding electronic signals to growing nerves can train them to perform "lost" functions, this combining of growing nerves with interfaced neurochips holds many possibilities. If you add the right stem cells and growth factors to the mix, you may be able to do restorative wonders to the central nervous system.Restoring control of muscles to the previously paralyzed, and restoring control of parts of the brain previously lost to injury or disease, is just the first step. The next step is brain:electronic interface for controlling prosthetic actuators, and actuators that are completely separate from the body.It is not difficult to imagine thought control over a look-alike robot, that can be sent as a proxy to conduct business, give lectures, or other more intriguing possibilities. Likewise, controlling a remote robot that looks exactly like someone else would allow someone to leave a long trail of false clues.This really is a "Brave New World" that we are entering.Hat tip Medgadget.
