Interface turns handwriting brain signals into text

As reported in the journal
Nature, a clinical trial participant with cervical spinal cord injury used the system to “type” words on a computer at a rate of 90 characters per minute, more than double the previous record for typing with a brain-computer interface. The participant had to merely think about the hand motions involved in creating written letters to complete the task.
The research team is hopeful that such a system could one day help to restore people’s ability to communicate following paralysis caused by injury or illness.

INDIANAPOLIS Patients who suffer from traumatic brain injuries (TBI) often need a great deal of healthcare services after the injury, but the extent of care utilization is unknown. A new study from research scientists affiliated with the U.S. Department of Veterans Affairs (VA), Regenstrief Institute and IUPUI is one of the first to analyze how much care TBI patients use and identify areas of unmet need. ....

New wireless system can restore communication and mobility in people with paralysis

New wireless system can restore communication and mobility in people with paralysis
Brain-computer interfaces (BCIs) are an emerging assistive technology, enabling people with paralysis to type on computer screens or manipulate robotic prostheses just by thinking about moving their own bodies. For years, investigational BCIs used in clinical trials have required cables to connect the sensing array in the brain to computers that decode the signals and use them to drive external devices.
Now, for the first time, BrainGate clinical trial participants with tetraplegia have demonstrated use of an intracortical wireless BCI with an external wireless transmitter. The system is capable of transmitting brain signals at single-neuron resolution and in full broadband fidelity without physically tethering the user to a decoding system. ....
