People with paralysis can control robotic devices through thought alone. Researchers at UC San Francisco have achieved a remarkable breakthrough in brain-computer interface (BCI) technology, enabling individuals with paralysis to control robotic devices through thought alone. This innovation combines artificial intelligence (AI) with neuroscience, allowing a paralyzed man to manipulate a robotic arm by imagining movements, a feat that marks a significant milestone in restoring autonomy to people with severe motor impairments. The device, known as a brain-computer interface (BCI), represents a fusion of advanced AI and neural engineering. BCIs have previously struggled to maintain functionality over extended periods, often losing effectiveness after just one or two days.

BrainGate researchers have recently made a major breakthrough in the area of brain-computer interfaces (BCIs) after clinical trial participants with tetraplegia demonstrated use of an intracortical wireless BCI with an external wireless transmitter. It was the first time such a system was used, and it is capable of transmitting brain signals at single-neuron resolution.

"We're taking subperceptual touch events and boosting them into conscious perception," says first author Patrick Ganzer, a principal research scientist at Battelle. "When we did this, we saw several functional improvements. It was a big eureka moment when we first restored the participant's sense of touch." The participant in this study is Ian Burkhart, a 28-year-old man who suffered a spinal cord injury during a diving accident in 2010. Since 2014, Burkhart has been working with investigators on a project called NeuroLife that aims to restore function to his right arm. The device they have developed works through a system of electrodes on his skin and a small computer chip implanted in his motor cortex.

Researchers have revealed that brainwaves can be used to steal online passwords. A team at the University of Alabama at Birmingham found brainwave-sensing headsets, also known as EEG or electroencephalograph headsets, put users at risk. They have become commonplace both as medical devices but also as game controllers, ranging in price from $150 to $800. Researchers say EEG devices and future brain computer interfaces can be hacked to monitor what a user is typing. Elon Musk's latest company Neuralink is working to link the human brain with a machine interface by creating micron-sized devices.

In the 1995 film "Batman Forever," the Riddler used 3-D television to secretly access viewers' most personal thoughts in his hunt for Batman's true identity. By 2011, the metrics company Nielsen had acquired Neurofocus and had created a "consumer neuroscience" division that uses integrated conscious and unconscious data to track customer decision-making habits. What was once a nefarious scheme in a Hollywood blockbuster seems poised to become a reality. BCIs use brain signals to control objects in the outside world. They're a potentially world-changing innovation – imagine being paralyzed but able to "reach" for something with a prosthetic arm just by thinking about it.
