Implanted electrodes + algorithm allow thought-driven 4 limb exoskeleton control

Alim Louis Benabid and Clinatec/University of Grenoble colleagues have developed a brain computer interface controlled exoskeleton that enabled a tetraplegic man to walk and move his arms.  Two 64 electrode brain implants drove the system. Benabid explained the benefits, stating that “previous brain-computer studies have used more invasive recording devices implanted beneath the outermost membrane of the […]

CTRL-Labs acquired by Facebook for 500M – 1B

Congratulations to CTRL-Labs and Lux Capital on Facebook’s acquisition of the four year old Neurotech startup. The company, whose technology assists in decoding brain activity and intention, will join Facebook’s AR/VR team. CTRL-Labs participated in a recent ApplySci panel of startups at Stanford led by Lux Capital’s Shahin Farshchi. Facebook presented its Brain Computer Interface work at the […]

BCI reads whole words from thoughts; no virtual keyboard necessary

Edward Chang at UCSF, Mark Chevillet at Facebook, and colleagues, have published a study where implanted electrodes were used to “read” whole words from thoughts.  Previous technology required users to spell words with a virtual keyboard. Subjects listened to multiple-choice questions and spoke answers aloud.  An electrode array recorded activity in parts of the brain […]

Study: Noninvasive BCI improves function in paraplegia

Miguel Nicolelis has developed a non-invasive system for lower-limb neurorehabilitation. Study subjects wore an EEG headset  to record brain activity and detect movement intention. Eight electrodes were attached to each leg, stimulating muscles involved in walking.  After training, patients used their own brain activity to send electric impulses to their leg muscles, imposing a physiological gait. With […]

Thought generated speech

Edward Chang and UCSF colleagues are developing technology that will translate signals from the brain into synthetic speech.  The research team believes that the sounds would be nearly as sharp and normal as a real person’s voice. Sounds made by the human lips, jaw, tongue and larynx would be simulated. The goal is a communication method for […]

Thought controlled tablets

The BrainGate/Brown/Stanford/MGH/VA consortium has published a study describing three teraplegic patients who were able to control an off the shelf tablet with their thoughts. They surfed the web, checked the weather and shopped online. A musician played part of Beethoven’s “Ode to Joy” on a digital piano interface. The BrainGate BCI included a small implant that […]

Thought controlled television

Samsung and EPFL researchers, including Ricardo Chavarriaga, are developing Project Pontis, a BCI system meant to allow the disabled to control a TV with their thoughts. The prototype uses a 64 sensor headset plus eye tracking to determine when a user has selected a particular movie. Machine learning is used to build a profile of […]

Brain-to-brain communication interface

Rajesh Rao and University of Washington colleagues have developed BrainNet, a non-invasive direct brain-to-brain interface for multiple people.  The goal is a social network of human brains for problem solving. The interface combines EEG to record brain signals and TMS to deliver information to the brain, enabling 3 people to collaborate via direct brain-to-brain communication. […]
