Our in was that we already have multielectrode arrays chronically placed in people with tetraplegia as part of the @BrainGateTeam clinical trial to restore movement and communication.

Why this is the case is a fascinating open question. It may be that if these are effective computational strategies for generating the right muscle commands for arm and hand movements, then they’re also well-suited for generating speech-producing muscle commands. 14/

Another open question is whether finding this activity in "arm" motor cortex is due to remapping because of the participants' tetraplegia. We don't think this is the case, but a definite answer is elusive because we'd need intracortical recording in able-bodied people. 15/15

Shout-out to lab alum
