A Neuralink voice-over explained that the company “records from more than 2000 electrodes implanted in the regions of the monkey’s motor cortex that coordinate hand and arm movements,” Reuters reported. “Using these data, we calibrate the decoder by mathematically modelling the relationship between patterns of neural activity and the different joystick movements they produce.
