A new brain-computer interface (BCI) powered by artificial intelligence (AI) allowed a paralyzed man, who could not speak or move, to control a robotic arm to grasp and move objects simply by imagining himself performing these movements.
Notably, the BCI worked for 7 months without needing to be adjusted, compared with just a day or two for other devices.
In an interview with Medscape Medical News, neurologist Karunesh Ganguly, MD, PhD, with University of California San Francisco (UCSF) Weill Institute for Neurosciences, explained that older BCI systems use spike recordings from tiny electrodes implanted in brain tissue to record signals from single or small groups of neurons near the electrode. However, these signals are unstable due to brain movement.
