What do brain computer interfaces do?
BCI technology allows a human brain and an external device to talk to one another—to exchange signals. It gives humans the ability to directly control machines, without the physical constraints of the body.
How did Neuralink start?
Tesla boss Elon Musk said in an interview late Sunday that a monkey has been wired up to play video games with its mind by a company he founded called Neuralink. Neuralink put a computer chip into the monkey’s skull and used “tiny wires” to connect it to its brain, Musk said.
How can brain-computer interface change our lives?
The development of BCI technology was initially focused on helping paralyzed people control assistive devices using their thoughts. But new use cases are being identified all the time. For example, BCIs can now be used as a neurofeedback training tool to improve cognitive performance.
How do brain-computer interfaces work?
Brain-computer interfaces (BCI) are systems that allow communication between the brain and various machines. They work in three main steps: collecting brain signals, interpreting them and outputting commands to a connected machine according to the brain signal received.
Are brain-computer interfaces (BCI) the future?
Sarah Marsch, Guardian news rep o rter, said “ Brain-computer interfaces (BCI) aren’t a new idea. Various forms of BCI are already available, from ones that sit on top of your head and measure brain signals to devices that are implanted into your brain tissue.” ( source)
How machine learning and artificial intelligence are used in BCI?
Artificial intelligence or Machine learning has received great attention for the development of BCI applications to solve difficult problems in several domains, in particular, medical and robotic fields. AI/ML has since become the most efficient tool for BCI systems. (source)
What is the best way to measure brain activity?
The most well known are EEG and fMRI, but there are others as well. EEG measures the electrical activity of the brain, fMRI the blood-flow in the brain. Each of these methods have their own dis/advantages.
