Monkeys Adapt Robot Arm as Their Own

FiReaNGeL writes "Neurobiologists from the Duke University Medical Center are training monkeys to use their brain signals to control a robotic arm; but they are not just learning to manipulate an external device. Rather, "their brain structures are adapting to treat the arm as if it were their own appendage", via a brain-implanted chip. "The finding has profound implications both for understanding the extraordinary adaptability of the primate brain and for the potential clinical success of brain-operated devices to give the handicapped the ability to control their environment", said the researchers. Read the story here with full details."

more interesting to me, it could be used as a very high-bandwidth connection between a computer and me.

This has already been done several times, both at a low-bandwidth level (electrodes on the skull, done several years ago), and a high-bandwidth level (implanting an electrode directly in the neocortex, done in 2000)

Here's the abstract, if you don't want to wade through the PDF:

We describe an invasive alternative to externally applied brain-computer interface (BCI) devices. This system requires implantation of a special electrode into the outer layers of the human neocortex. The recorded signals are transmitted to a nearby receiver and processed to drive a cursor on a computer monitor in front of the patient. Our present patient has learned to control the cursor for the production of synthetic speech and typing.
