Bionic finger, implanted electrodes, enable amputee to “feel” texture

Swiss Federal Institute of Technology and Scuola Superiore Sant’Anna researchers have developed  a bionic fingertip that allows amputees to feel textures and  differentiate between rough and smooth surfaces. Electrodes were surgically implanted into the upper arm of a man whose arm had been amputated below the elbow.  A machine moved an artificial finger, wired with electrodes,  across […]

BCI controlled wheelchair

Miguel Nicolelis has developed a brain computer interface that allows monkeys to steer a robotic wheelchair with their thoughts.  The study is meant to demonstrate the potential of humans to do the same. Signals from hundreds of neurons simultaneously recorded in two brain regions were translated into the real-time operation of a wheelchair. Nicolelis said: “In […]

Brain state learning system adapts to user focus

BACh (Brain Automated Chorales) estimates brain workload using fNIRS to measure oxygen in the prefrontal cortex to help beginners learn to play Bach chorales.  The system offers new lessons when the brain isn’t overloaded with information. Tufts Beste Yuksel and Robert Jacob, who developed the technology, believe that it can help with any type of learning, and specify math, […]

DARPA neural implant to enhance brain-computer connections

DARPA is leading the development of an improved  neural implant for connecting the brain to computers, using advances neuroscience, synthetic biology, low-power electronics, photonics and medical manufacturing.  Their goal is to to dramatically enhance  neurotechnology research capabilities and provide a foundation for new therapies. The Neural Engineering System Design program aims to produce a miniaturized brain implant, smaller […]

Faster, noninvasive BCI speller system

Tsinghua University researchers have developed  a noninvasive brain-computer interface with the fastest information transfer rate to date.   The system is based on  steady-state visual evoked potentials, where a speller system detects a user’s gaze direction to a target a character. Frequency and phase of stimulation signals were precisely encoded in single-trial SSVEPs. A user-specific decoding algorithm adjusted to […]

Brain-to-brain link allows one person to read another’s thoughts

University of Washington researchers used a direct brain-to-brain connection to enable pairs of participants to play a question-and-answer game by transmitting signals from one brain to the other over the Internet. The experiment is thought to be the first to show that two brains can be directly linked to allow one person to guess what’s on another person’s mind.
