Auditory-Reliant Intracortical Brain Computer Interfaces for Effector Control by a Person with Tetraplegia.

Brain computer interfaces (BCI) have been successful in enabling control of external effectors, such as a computer cursor or robotic arm by people with severe motor impairment. While current usage relies heavily on the users’ ability to reliably utilize visual feedback from the interface, a visual-based BCI can be difficult or even unfeasible to use by people whose paralysis is accompanied by limitations of eye movements or vision. Here we present a novel auditory paradigm, and present pilot data from a person with tetraplegia performing a BCI task with auditory cues.
