Scalp recording of the P300 event-related potential enables a patient with “locked in” syndrome to type words using only his brain.

Greg Bieker experienced a traumatic brainstem stroke that rendered him quadriplegic with locked in syndrome two decades prior to his introduction to BCI technology. Now, an EEG headset records event related potentials that allow him to type words and communicate using only his brain.

Electrocorticography of the motor cortex increases spinal cord functioning in a patient following complete spinal cord injury.

Keith Thomas is a patient who became paralyzed from the chest down following a diving accident that resulted in a complete spinal cord injury; but after surgical implantation of BCI devices, Keith is learning to use his arms again. Patients with life-altering BCI experiences like that of Keith Thomas may be exceptions to the norm in today’s world, but in the near future, this type of influence of BCI will be ubiquitous.
