Researchers at Brown University have created a brain-computer interface (BCI) with 200 electrodes providing 48 megabits per second (Mbit/s) of neural signals

The trial participants – a 35-year-old man and a 63-year-old man, paralysed by spinal cord injuries – were able to use the BrainGate system in their homes, not a lab setting . Unencumbered by cables, they used the BCI continuously for up to 24 hours, giving researchers long-duration data, including while the participants slept.

Brown University has an agreement with neural engineering and neuroprosthetics company Blackrock Microsystems, to make the device available for researchers around the world.
