Brandon Patterson, paralyzed from the chest down after a car crash nine years ago, depends on family help for daily tasks like getting out of bed or pouring coffee. But scientific progress has offered him a new role—not just a test subject, but an active participant in pushing boundaries. Unlike typ
Utah arrays are tiny devices that help people and animals communicate with computers using their brains. They pick up electrical signals from the brain to control things like prosthetic limbs or restore senses. But there's a big problem: small movements between the array and the brain can cause stra
A new company is making waves in the world of blindness treatment. They're using a tiny implant to help people see again. The implant, called PRIMA, is about the size of a pinhead. It's placed under the retina, the part of the eye that processes light. The implant works with a special pair of glasse
Brain-computer interfaces (BCIs) are making waves, but they're not perfect. The current tech, which relies on EEGs, is a bit of a mystery. It's like having a puzzle with missing pieces. You see the big picture, but you're not sure how it all fits together. The main issue? EEGs pick up brain signals
Brain-computer interfaces (BCIs) are like translators between our brains and machines. They need to be super accurate to be useful. But, using just one type of model to read brain signals isn't always the best. That's where hybrid models come in. They combine different types of models to get better
People are talking about brain-computer interfaces (BCIs) a lot lately. These gadgets let users control devices just by thinking about it. For some, this sounds like a dream come true. For others, it's a bit of a nightmare. A closer look at public opinions over the last decade shows a mix of excite
The world of brain-computer interfaces (BCIs) is making waves. These tools have the power to bring back speech for people who have lost it due to neurological issues or injuries. BCIs can turn brain signals into text. But text alone can't capture the full richness of human speech. It misses out on t
Wearable tech is taking a leap forward. It is now possible to turn thoughts into art. Brain-computer interfaces (BCIs) are stepping out of labs and into the world of art. These interfaces read brain signals and turn them into visual and physical expressions. Two cool projects show how this works.
The brain is a complex organ that generates electrical signals. These signals can be captured and analyzed using electroencephalography (EEG). One big challenge in brain-computer interfaces (BCI) is figuring out which EEG signals are important and which ones are just noise. This is where feature sel
Imagine controlling a computer just by thinking about it. Sounds like science fiction, right? Well, it's not. In 2024 and 2025, some amazing surgeries using brain-computer interfaces (BCIs) made big news. These surgeries let paralyzed people use computers with just their thoughts. This isn't new. Pe
