New Tasks Become as Simple as Waving a Hand with Brain-Computer Interfaces

Researchers show that when humans use brain-computer interface technology, the brain behaves much like it does when completing simple motor skills such as waving a hand. This technology could help improve the daily lives of those who are paralyzed or lost specific abilities due to neurodegenerative diseases. Read More

Sense of Touch Reproduced Through Prosthetic Hand

Artificial sensors in a prosthetic hand allows rhesus macaques to sense tactile stimulus, according to a new study. A similar device could be used in human trials within the next year, researchers hope. Read More

Human Brain Treats Prosthetic Devices as Part of the Body

According to new research, the human brain can adapt to treat a relevant prosthetic as a substitute for a person's non-working body part, and not as an extension to their immobile limb. Read More

Researchers Describe Technology that Lets Spinal Cord Injured Man Control Robot Arm with Thoughts

Researchers describe how an electrode array sitting on top of the brain enabled a 30-year-old paralyzed man to control the movement of a character on a computer screen in three dimensions with just his thoughts. It also enabled him to move a robot arm to touch a friend’s hand for the first time in the seven years. Read More

New Brain Circuit Sheds Light on Development of Voluntary Movements

A research team describes the entire network of brain cells that are connected to specific motor neurons controlling whisker muscles in newborn mice. A better understanding of such motor control circuits could help inform how human brains develop, potentially leading to new ways of restoring movement in people who suffer paralysis from brain injuries, or to the development of better prosthetics for limb replacement.

Scientists Use Prosthetic Device to Restore and Improve Impaired Decision Making Ability in Animals

Scientists used an electronic prosthetic system to tap into existing circuitry in the brain at the cellular level and record the firing patterns of multiple neurons in the prefrontal cortex, the part of the brain involved in decision-making. They then “played” that recording back to the same brain area to electrically stimulate decision-based neural activity. Not only did it restore function, in some cases, it also improved it.
