Rerouting Brain Circuits with Implanted Chips

A new, implantable and wireless brain chip can create artificial connections between different parts of the brain, paving the way for devices that could reconnect damaged neural circuits. Scientists say the chip sheds light on the brain’s innate ability to rewire itself, and it could help explain our capacity to learn and remember new information. “We have a chance of manipulating and repairing [specific] regions of the brain that might be damaged,” says Joseph Pancrazio, director of the neural-engineering program at the National Institute of Neurological Disorders and Stroke in Bethesda, MD. “To be able to repair these kinds of lesions on a neuron-by-neuron basis is extraordinary.”
