Brain Computer Interface: What It Is, Why You Should Care

A brain-computer interface (BCI) is a direct communication pathway between the brain and an external device. The idea of BCI was first conceptualized by Leonardo da Vinci in 1590, but it wasn’t until recently that scientists have made any real headway in developing a working model for one. In recent years, with improvements in brain imaging technology, computer processing power and artificial intelligence systems, brain-computer interfaces have become more advanced than ever before. This article will explain what they are and why you should care about them!

What is Brain Computer Interface (BCI)

A brain-computer interface (BCI) is any system that acts as an intermediary brain activity. This means it can take information from the brain and use this to control another device or computer, or vice versa. The most common forms of BCIs are EEGs (electroencephalograms), which measure brain electrical activity noninvasively. They are a good way to measure brain activity in general, but can’t tell what kind of brain activity is being measured.

The most common BCI today uses EEG brain signals to control computer cursors or robots. However, there have been many advances in this technology which mean they could be used for more than just basic cursor movement. For example, brain-computer interfaces for communication and brain-computer interfaces that can be used by people who are paralysed or locked in.

In the future, BCIs could enable communication via brain signals alone, allow us to control artificial limbs with our thoughts – even give us super-human senses such as infrared vision. In general it is a good idea to keep an open mind about brain-computer interfaces.

Why You Should Care!

BCIs will bring many benefits to the medical field, social interaction and more. They can help with brain-related disorders like paralysis or language impairments; they could potentially replace prosthetic limbs; raise our understanding of brain activity (and its implications); or even enhance human capabilities beyond what we are currently capable of.

In fact brain computer interface is already here, you just have to know where to look! Elon Musk’s company Neuralink was founded in 2016 and they are a brain-computer interface venture based out of San Francisco. Their goal is for brain interfaces to be used by people with disabilities first, but eventually everyone could benefit from their technology.

The brain computer interface is a rapidly evolving and exciting field. What we could do with brain-computer interfaces in the future will be limitless! Brain computer interface helps people recover from disabilities, it allows us to understand brain activity better than ever before.

Brain Computer Interface uses today

The brain computer interface helps people recover from disabilities by giving them the ability to control their environment through thought alone.

Brain computer interfaces allow us to understand brain activity better than ever before, which will help advance neuroscience and medicine in many ways. Brain-computer interfaces today are used for basic things like moving a cursor on screen or controlling robotic arms with your mind, but it could expand into something much broader in scope soon enough!

It is because of how quickly brain-computer interfacing technology is evolving that you should be excited about its future possibilities. As brain computer interface continues to improve we’ll see more applications emerge that will change our lives forever! Things like recording memories, downloading data to your brain, and much more. These ideas sound crazy right now, but it will be a reality before we know it!

Brain Computer Interface future possibilities

What would you do with a brain computer interface in the future? The possibilities are limitless! We could communicate brain to brain, we can create cyborgs and who knows what else! All I know is that the future of brain computer interface looks very bright.

The brain-computer interfaces of today and tomorrow are going to help us in many ways. Brain-computer interfaces today are used for basic things like moving a cursor on screen or controlling robotic arms with your mind, but it could expand into something much broader in scope soon enough.

Imagine a world where we can communicate with each other directly through our minds and not just words?

The brain, the organ that runs our entire body, still has so much we don’t know about it or how to use it properly. It’s important that we continue learning as much as we can about ourselves and what all of those neurons firing off means in relation to everything else going on inside us. With knowledge comes power and this will help us better understand our brains which could affect every aspect of life.

Can you buy a Brain Computer Interface?

Brain computer interface is still not something you can buy in stores or online, but there are brain-computer interfaces that let people play video games with their thoughts.

There’s no brain-computer interface for dummies (yet), but it will come soon enough as companies like Neuralink develop this technology further.

Is Brain Computer Interface safe?

Brain-computer interfaces aren’t completely safe, but they’re safer than brain surgery.

The brain is a very delicate organ that shouldn’t be messed with unless it’s absolutely necessary and companies like Neuralink are making sure to take all the right precautions before going forward with brain computer interface research.

Can BCI be hacked?

Brain-computer interface can’t be hacked, but brain hacking is a different story.

When it comes to brain computer interfacing, companies are doing everything they can to protect against hackers who might want to take control of the brain. However, when you start tampering with artificial intelligence and neural networks there’s always going to be some risk involved because you’re going into uncharted territory.


In conclusion brain computer interface is a great technology that will help people with disabilities and open up new doors to artificial intelligence. However, there are still some kinks being worked out before the full potential of brain computer interfaces can be realized.
