Vocalizations Return to Paralyzed Man, Via Wireless Brain-Computer Interface
Locked-In Syndrome is one of the most terrifying brain lesions -- leaving patients aware but almost entirely without the power to move. Now, a collaboration of American academic researchers has implanted a wireless brain-machine interface, developed by Neural Signals of Duluth Georgia, into a locked-in subject who is almost completely paralyzed.
The system uses brain electrodes to read signals meant for jaw and mouth muscles. An FM radio is used to transmit these brain signals to a computer, which transforms them into recognizable sounds. Currently the system is only able to produce vowels, but with more electrodes and more powerful algorithms it should be able to scale up to fully vocalized words.
