What Is Brain-Computer Interface (BCI)?

We don't know about you, but We've always been fascinated by the idea of a brain-computer interface (BCI). What if we could think of something, and it would happen? What if we could control things with our minds? What if we didn't need keyboards or mice or touch screens? What if all we had to do was think? It's a lot like how dogs get to live in a world without pants. They have to go outside and pee on stuff. And guess what? They're not even ashamed! The fact that they don't have any shame is part of what makes them great. It's like they've achieved enlightenment about their bodies that humans can only dream about. Okay, sorry. That got weird there for a second. But anyway. BCIs are pretty cool. BCIs are being used for all sorts of things these days! For example, people who have lost their speaking ability due to injury or disease can use BCIs to communicate with others. Some people with disabilities have also used them to control wheelchairs and other assistive devices. In addition, BCIs are being studied as possible treatments for neurological disorders such as epilepsy and Parkinson's Disease. In medicine, there are two main types of BCIs: invasive and non-invasive. Non-invasive BCIs measure electrical activity in the brain through electrodes placed on the scalp or implanted directly into your brain tissue (electrocorticography). Invasive BCIs use electrodes inserted directly into your brain tissue via a small hole drilled in your skull (called intracranial electroencephalography). In virtual reality. Scientists have been working on brain-computer interface technology for decades, and the results are finally here. What used to be a crazy idea is now a reality. The first BCI devices recorded signals from the brain and translated them into commands that could be used to control external devices. More modern BCI technologies are designed as implants that improve skills associated with specific brain activities, such as vision, hearing or other human or animal functions. A range of these devices, called neuroprosthetics, have been developed and are used worldwide as a practical means of assisting human capabilities.
