Brain-Computer Interfaces Can Decode Movement Intent—But Signal Instability Is the Real Problem
Mechanism: Brain-Computer Interfaces initially decode motor cortex neural activity to control a robotic arm. Readout: Readout: Signal stability and performance scores decline dramatically from 100% to 20% and 95% to 15%, respectively, within weeks.
We can read minds, sort of. Electrodes in motor cortex record neural activity that correlates with arm movements. Decoding algorithms translate that activity into cursor control or robotic arm commands. The technology works. The problem is it stops working after a few weeks.
