Synchron's blood-vessel implant can detect eye movements from brain signals
A Journal of Neural Engineering study in one person with ALS is the first demonstration of an eye-movement BCI using endovascular recordings.
Researchers from the University of Melbourne and Synchron report that the company’s Stentrode, implanted in a blood vessel next to the brain, can detect when a person makes rapid eye movements (saccades) and, to some extent, in which direction. In one participant with ALS, the decoder distinguished saccades from steady gaze with good reliability (an AUC of 0.88).
The authors call it the first proof of concept for an eye-movement BCI using endovascular recordings. Eye-movement signals could add another control channel for people who are losing other muscle control.
