Helping Stroke Victims Communicate
From: Wireless Design & Development - 10/13/2014

Researchers at East Tennessee State University have shown that a
brain-computer interface (BCI) device can be beneficial to patients who have
suffered a brainstem stroke and are experiencing "locked-in" syndrome and
have no ability to communicate with the outside world.

The BCI records a common brain response called the P300 using small sensors
placed on the scalp.

The P300 becomes a "virtual finger" for a typing device, so when a letter or
number flashes before a patient, a P300 occurs and a computer screen displays
the words and sentences that the patient is trying to communicate.
