Neuroscience 2022: Recording brain signals to restore talk and movement

Nov. 14, 2022
By Mar de Miguel
Stimulating the brain via implanted electrodes is used to treat both movement disorders such as Parkinson’s disease, and some psychiatric conditions such as obsessive compulsive disorder. But researchers are also working on ways to make such implanted electrodes listen instead of talk – and translate neuronal signals for people that have lost the ability speak, or the ability to move. At the Neurophysiology: Decoding and Neural Processing II session of the 2022 Annual Meeting of the Society for Neuroscience in San Diego, researchers from the Wyss Center for Bio and Neuroengineering (Switzerland) presented a device implanted in the brain that allowed restoration of movement and speech.

Synchron brain-computer interface enables first thought-to-tweet

Jan. 4, 2022
By Annette Boyle
Synchron Inc. closed out 2021 by providing an opening for a patient with amyotrophic lateral sclerosis (ALS) to send the first thought transferred to a tweet via an implantable brain computer interface. Philip O’Keefe, who received one of the company’s Stentrode implants in April 2020, took over the Twitter account of Sychron CEO Thomas Oxley to say, “Hello, World. Short tweet. Monumental progress.”

Brain-computer interface implant wins breakthrough device designation

Nov. 17, 2021
By Catherine Longworth
The FDA granted Blackrock Neurotech LLC breakthrough device designation for its Moveagain brain-computer interface (BCI) system as it targets 2022 for commercialization of the neural implant. Earlier this year, the Salt Lake City-based company received $10 million from investors including, Re.Mind Capital, Sorenson Impact and Facebook investor Peter Thiel to expand its clinical program. The company said its technology could be key to providing tetraplegic patients the ability to control devices directly from the brain.

US government eyes export controls for brain-computer interface devices

Oct. 25, 2021
By Mark McCarty
The brain-computer interface (BCI) is the subject of keen medical interest for those dealing with neurological damage, but military applications are also a point of interest among a number of national governments. With all this in mind, an agency at the Department of Commerce has posted a request for comments regarding a possible imposition of export controls on BCI devices due to national security concerns, a proposal that could complicate exports of such devices for medical use.

Brain implant evokes sensation in fingers, may show path to restoring sense of touch

Aug. 17, 2021
By Annette Boyle
Using a minimally invasive brain implant, Feinstein Institutes for Medical Research scientists produced tingling sensations in the fingers of patients who lacked the sense of touch as a result of nerve damage, according to a study published in Brain Stimulation. A second study by the team, which appeared in Frontiers in Neuroscience, used stereoelectroencephalography (SEEG) electrodes to decode neural signals to improve the hand control algorithms in brain-computer interfaces.

FDA mum on enrollment expectations for studies of brain-computer interface devices

July 29, 2021
By Mark McCarty
The FDA’s device center has a mantra of sorts when it comes to the details, or lack thereof, in guidance, which is “talk to us early and often.” For device makers eyeing the brain-computer interface (BCI) device space, this mantra has been applied to the question of pivotal study enrollment numbers, suggesting that some sponsors will find their pivotal studies come with a case of sticker shock sufficient to force them to rethink their research and developmental plans.

FDA deems brain-computer interface guidance a leapfrog document

June 16, 2021
By Mark McCarty
With paralysis affecting more than 5 million Americans, devices that serve as brain-computer interfaces (BCIs) are increasingly important, even if few are commercially available. The FDA has responded to the predicament with a leapfrog guidance, a preliminary form of guidance designed to foster more interaction with industry and encourage developers to move along on development programs for devices that will aid patients in restoring lost motor and/or sensory capabilities.

AI-powered brain implant improves post-stroke mobility

Feb. 17, 2021
By Annette Boyle
Researchers at Thomas Jefferson University have implanted brain electrodes in a patient who suffered a subcortical ischemic stroke more than a year ago to help them overcome abnormal muscle tone and control a robotic arm brace. Artificial intelligence (AI) algorithms interpret neuronal signals recorded by the electrodes into movement of the brace.

FDA grants breakthrough designation to Synchron’s Stentrode brain-computer interface

Aug. 28, 2020
By Liz Hollis
Neurovascular bioelectronics medicine company Synchron Inc. has received good news in the form of a breakthrough device designation for its Stentrode. The U.S. FDA granted the designation for the fully implantable medical device that can translate brain activity or stimulate the nervous system from inside a blood vessel. As a bonus for patients, the device does not require open brain surgery. “As this is a first-of-its-kind device, we look forward to working closely with the FDA to prioritize development of the Stentrode and ensure access for patients with paralysis, as well as lay the groundwork for future indications for brain-computer interfaces,” said Thomas Oxley, CEO of Synchron.
