![]() ![]() “Then we started to give her some control,” says Jennifer Collinger, a biomedical engineer at Pittsburgh and the first author on the study. All the while, the computer was recording neural activity in her motor cortex, and this information was used to better decode her intentions into movements of the robot arm. “After the electrodes were implanted into her brain, began her training by watching the arm move and imagining that she was controlling it. The complexity and number of electrode connections is about twice as many as the researchers have attempted in the past, and the sophistication of the circuitry gives the woman a more “natural and realistic movement of the arm and hand”. ![]() Each chip is connected to 96 electrodes that are wired through the woman’s skull to a robotic arm. Researchers from the University of Pittsburgh implanted two 4mm by 4mm chips into the woman’s motor cortex, the part of the brain responsible for body movements. The most advanced brain-computer interface for operating a robotic arm has given a woman paralyzed from the waist down a new lease on life.
