Israeli researchers have developed a computer interface that translates nasal pressure into control signals, which enables the communication of paralyzed people suffering with “locked-in” syndrome.

A widely distributed neural network was shown using FMRI of interface usage, while the interface shared neural substrates with language production.
Locked-in syndrome is characterized by intact cognition yet complete paralysis. Hence, these individuals are “locked-in” their own body, at best able to communicate using eye blinks alone.
