BCI–Based Communication in the Completely Locked-In State

The study, published in PLoS Biology, detailed the researchers’ efforts in developing a non-invasive method to allow four completely locked-in patients to answer “yes or no” questions. The technique involves patients wearing a cap that uses infrared light to measure blood flow in different areas of the brain when they think about responding “yes” or “no” to a question. 

The researchers trained the patients by asking them control test questions to make sure the system could accurately record their answers, before asking questions about their current lives.
