Noninvasive electroencephalogram based control of a robotic arm for reach and grasp tasks

“Brain-computer interface (BCI) technologies aim to provide a bridge between the human brain and external devices. Prior research using non-invasive BCI to control virtual objects, such as computer cursors and virtual helicopters, and real-world objects, such as wheelchairs and quadcopters, has demonstrated the promise of BCI technologies. However, controlling a robotic arm to complete reach-and-grasp tasks efficiently using non-invasive BCI has yet to be shown. In this study, we found that a group of 13 human subjects could willingly modulate brain activity to control a robotic arm with high accuracy for performing tasks requiring multiple degrees of freedom by combination of two sequential low dimensional controls. Subjects were able to effectively control reaching of the robotic arm through modulation of their brain rhythms within the span of only a few training sessions and maintained the ability to control the robotic arm over multiple months. Our results demonstrate the viability of human operation of prosthetic limbs using non-invasive BCI technology.”

EEG Neurofeedback: Application in ADHD and Epilepsy


The use of electroencephalogram neurofeedback has been studied in a number of psychiatric disorders, especially for the treatment of attention deficit/hyperactivity disorder (ADHD). However, many clinicians are not aware of this treatment and the level of evidence supporting its use. In this article, we review the evidence for the efficacy of neurofeedback in several psychiatric disorders and also discuss the specific neurofeedback protocols that have been found effective in the treatment of ADHD, such as slow cortical potential, theta/beta ratio, and sensorimotor rhythm neurofeedback.

Touched by Science: Paralyzed Man Feels Again Through Mind-Controlled Robotic Arm

Imagine being in an accident that leaves you unable to feel any sensation in your arms and fingers. Now imagine regaining that sensation, a decade later, through a mind-controlled robotic arm that is directly connected to your brain.

That is what 28-year-old Nathan Copeland experienced after he came out of brain surgery and was connected to the Brain Computer Interface (BCI), developed by researchers at the University of Pittsburgh and UPMC. In a study published online today in Science Translational Medicine, a team of experts led by Robert Gaunt, Ph.D., assistant professor of physical medicine and rehabilitation at Pitt, demonstrated for the first time ever in humans a technology that allows Nathan to experience the sensation of touch through a robotic arm that he controls with his brain.

Team Brain Tweakers won Gold in the BCI Race at Cybathlon 2016

“The Cybathlon took place on October 8th, 2016 at the ETH Zurich where people with disabilities competed side by side at the Brain-Computer Interface Race (BCI Race).

Pilot Poujouly Numa from the Team BrainTweakers won Gold in the BCI Race using his brain waves to control an avatar along a racetrack on a virtual train. The game is called “BrainRunners” and was especially developed for the Cybathlon’s BCI Race.”

You may be able to train your brain to be fearless


All your fears, stresses and anxieties have one thing in common. They are sensed by a pair of pea-sized patches of neurons, called the amygdala, sitting deep inside your brain. So what if you could control your amygdala? What if you could change your brain and become calmer and braver?

“Positive feedback” article on APA.ORG


In 2016, we have watches that count each step we take, phone applications that tally each calorie swallowed and burned, “smartshirts” that measure our heart rate and respiration. We are living in an era of personal data tracking — yet many experts say we’re missing a huge opportunity to use our body’s data to change our physiological activity for the better.

Biofeedback is hardly new; its therapeutic use dates back nearly 50 years. Yet the technique is easier than ever, says Paul Lehrer, PhD, a psychologist at Rutgers-Robert Wood Johnson Medical School.

Mapping the brain: ‘With this therapy, the brain can learn to fix itself’

“…he also had his own brain map made and went through therapy himself to learn to use his brain to control and “self-correct” his attention disorder. After about 35 sessions, he graduated from the program — and had the added benefit of seeing his migraines almost disappear and got the approval of his medical doctor to discontinue his ADHD medication.

“The brain wants to do well, it wants to improve,” Bindewald said. “At first, I was very skeptical … but with this therapy, the brain can learn to fix itself … I feel much more balanced now.”
