Default Bionic Arms Controlled By Man's thoughts

Quote:
Todd Kuiken, a biomechanical engineer at Northwestern University, and his team are looking at how different patterns of brain activity can be used to control prosthetic limbs.

In the video above, the nerves from Sullivan's stump were connected to muscles in his chest. When he thinks about moving his chest muscles, the signals are picked up by the nerves that were previously connected to the arm and interpreted by a computer which relays the information to the prosthesis.

"If you transfer the nerves [from the stump] to healthy muscles, then you can amplify the brain signals used to control the arm," says Nate Bunderson, now at the Georgia Institute of Technology, who presented the research to the Society of Neuroscience conference in San Diego at the end of last year. "We can use those signals to control the device."

The team has fine-tuned the system that interprets these brain signals, giving the patients control over a wider range of movements than was ever possible before.

Sullivan was the first to undergo the surgery about eight years ago and he still comes in to carry out tests. Whereas most amputees seem to lose control of these nerves over time, because they are no longer being used to control muscles, in patients like Sullivan, the signals appear to become stronger.

According to Bunderson, this effect could be due to the brain getting used to the re-wired pathways. "Instead of having muscles interpret the neural command, we now have a computer trying to interpret the neural command and the brain has to adjust to that."

Next, Kuiken's team wants to make the technology accessible to a greater number of patients. They plan to develop the system so it can be applied to less high-tech prosthetics currently on the market. Bunderson is looking to better understand how the brain adapts to prosthetics.
