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.
Researchers can control the behavior of monkeys by using pulses of blue light to very specifically activate particular brain cells. The findings represent a key advance for optogenetics, a state-of-the-art method for making causal connections between brain activity and behavior. Researchers say that similar light-based mind control could likely also be made to work in humans for therapeutic ends.
By decoding brain activity, scientists were able to ‘see’ that 2 monkeys were planning to approach the same reaching task differently – even before they moved a muscle.
NIH-funded study shows progress in brain-computer interface technology. In an ongoing clinical trial, a paralyzed woman was able to reach for and sip from a drink on her own – for the first time in nearly 15 years – by using her thoughts to direct a robotic arm. The trial, funded in part by the […]
As humans face increasing distractions in their personal and professional lives, University of British Columbia researchers have discovered that people can gain greater control over their thoughts with real-time brain feedback. The study is the world’s first investigation of how real-time functional Magnetic Resonance Imaging (fMRI) feedback from the brain region responsible for higher-order thoughts, […]
Thought control of prosthetic limbs via brain-controlled interfaces will be tested and developed with funding from DARPA. Human subjects will test neural interface systems used to control prosthetic limbs.
