New Scientist covers another step towards functional neural prosthetics. Development here will be slow and complex, but we now have sufficient proof of concept across the field to see that interfacing digital systems with out brains is quite possible. We’ll use that first to help those who’ve suffered brain damage of some sort, and then eventually to augment.
AN ARTIFICIAL cerebellum has restored lost brain function in rats, bringing the prospect of cyborg-style brain implants a step closer to reality. Such implants could eventually be used to replace areas of brain tissue damaged by stroke and other conditions, or even to enhance healthy brain function and restore learning processes that decline with age.
Now Matti Mintz of Tel Aviv University in Israel and his colleagues have created a synthetic cerebellum which can receive sensory inputs from the brainstem – a region that acts as a conduit for neuronal information from the rest of the body. Their device can interpret these inputs, and send a signal to a different region of the brainstem that prompts motor neurons to execute the appropriate movement.
“It’s proof of concept that we can record information from the brain, analyse it in a way similar to the biological network, and return it to the brain,” says Mintz, who presented the work this month at the Strategies for Engineered Negligible Senescence meeting in Cambridge, UK.
