“#A wireless BCI has been successfully tested on humans for the first time<\/strong>”<\/p>\n

\n Scientists have demonstrated the first human use of a wireless brain-computer interface, a potential breakthrough for people with paralysis.<\/p>\n

While traditional BCIs are tethered to users via cables, the new system \u2014 called BrainGate \u2014 replaces the cords with a small transmitter affixed atop a\u00a0users\u2019 head. The unit then connects to an electrode array implanted in the brain\u2019s motor cortex.<\/p>\n

In a clinical trial, two participants with paralysis used the system to point, click, and type on a standard tablet computer. They both achieved similar typing speeds and point-and-click accuracy as those attained with\u00a0wired systems.<\/p>\n

The researchers say it\u2019s the first time a device has\u00a0transmitted the full spectrum of signals recorded by a sensor in the brain\u2019s motor cortex.<\/p>\n

John Simera, the study\u2019s lead author, said the device was functionally equivalent to wired BCIs, but without the restrictions of cables:<\/p>\n

The signals are recorded and transmitted with app<\/a>ropriately similar fidelity, which means we can use the same decoding algorithms we used with wired equipment. The only difference is that people no longer need to be physically tethered to our equipment, which opens up new possibilities in terms of how the system can be used.<\/span><\/p>\n<\/blockquote>\n

The participants were also able to use the system in their homes, unencumbered by cables, for up to 24 hours.<\/p>\n

Leigh Hochberg, who leads the BrainGate clinical trials, said this allowed the team to understand how neural signals evolve over time:<\/p>\n

With this system, we\u2019re able to look at brain activity, at home, over long periods in a way that was nearly impossible before. This will help us to design decoding algorithms that provide for the seamless, intuitive, reliable restoration of communication and mobility for people with paralysis.\u201d<\/span><\/p>\n<\/blockquote>\n

The researchers will now use the insights to develop the\u00a0next generation of neurotechnologies. Ultimately, their study could take us a big step closer to fully-implanted BCIs.<\/p>\n
