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.”

Be a tree and share gratitude

“The more we feel threatened, the more we will interpret the events around us negatively. We become more stressed, defensive, and pessimistic.  If this response occurs frequently, it contributes to increased morbidity and mortality. We may not be in control of external or personal event; however, we may be able to learn how to change our reactions to these events.  It is our reactions and interpretations of the event that contributes to our ongoing stress responses. The stressor can be labeled as crisis or opportunity.

Here’s how you can plant feelings in people’s heads, Neuroscientists show

inception

“Planting new emotions in unwitting people’s minds is probably nothing short of a superpower. And scientists have done just that.

Using a relatively new brain-training technique known as neurofeedback, scientists at Brown University were able to make people develop positive or negative feelings about photographs toward which they’d previously felt no strong emotions.

In other words, they induced feelings where there were none ― and without the study participants even becoming aware of it.”

EEG Neurofeedback: Application in ADHD and Epilepsy

dogsz

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.

Unconscious brain training beats phobias without the stress

“Lau’s team are using software that can be trained to identify what people are looking at or imagining as they lie in fMRI brain scanners. This software can even identify things that someone is thinking about unconsciously, by focussing on activity in the visual cortex – the region that processes raw visual data from our eyes.”

People can consciously control mental activity using brain scans

People who can “see” their brain activity can change it, after just one or two neurofeedback sessions, new research shows.

People in the study were able to quiet activity in the amygdala — an almond-shaped brain region that processes emotions such as fear — after seeing simple visual or auditory cues that corresponded to the activity level there, according to a new study published in the Sept. 15 issue of the journal Biological Psychiatry. The findings reveal the incredible plasticity of the brain, the researchers said.

Having a Sense of Purpose in Life Improves Cognition, Mental Health

meaning_in_life

“Psychologists have found repeatedly that people with a strong sense of purpose in life tend to fare better on several different measures of mental health, well-being and even cognitive functioning.

Most recently, a team of researchers from Canada and the United States surveyed 3,489 adults between the ages of 32 and 84. They found that adults who reported a greater sense of purpose in life also tended to score higher on tests of memory and executive functioning.

While the reason for this relationship between purpose in life and cognition isn’t clear, the authors cite the importance of promoting “healthy cognitive and purposeful aging.”
