Brain-Computer Interface | How is computer control possible by human brain?

If you were to imagine the future of technology, what kind of images would come to your head? – Changing the TV channel without doing anything (not even remotely)? Play computer games with the help of the mind? Or display the gameplay directly in the head without playing the game on the monitor? Moving into the world of computer games? People’s minds fall? Your imagination seen on a computer screen? – While all these thoughts are insane, it is possible to make them busy with Brain – Computer Interfaces or BCI technology.

Modern computers are getting more and more sophisticated as they try to understand the human brain. And as a result. we can turn our imagination science fiction into a busy one. In this article, I will know how BCI works and discuss the feasibility of this technology. so let’s get started…

Brain’s electric signal

Why do we compare the human brain and computer and why we want to connect two or more? See computer is an electronic device made of plastic, transistors, IC, etc… but the human brain is a living thing. That is, made up of billions of tiny tiny cells called neurons. each nerve cell is connected by dendrites and axons.

Computers and the brain are completely different things. But Brain’s working style is very much like a computer’s. When we talk, act, think, or do anything – neurons work to complete the data. And while doing this, the neuron generates an electric signal that is shared from neuron to neuron. And, you know, electronics also works on electric signals. It is possible to connect the brain to the computer or the computer to the brain, based on this electric signal. Artificial neural networks and mind uploading technology work on this concept.

However, the electrical signals created by the brain can be read by scientists. that is, the various types of signals that are produced in our brain during different tasks, the scientists can capture that signal and understand what is produced for a task. For example. if you see red or green colors in front of your eyes. now the optic nerve will send a kind of electric signal to your brain.

And the data is zipped between those signals, exactly what color your eyes saw. Now if you can read that signal and send the same signal directly from the camera and send it directly to the brain, your brain will see the same color. thus making it possible for the camera to make the signal back to the blind. Because no matter how blind the eyes of the blind, their ability to recognize the signals in the brain is lost.

Brain-computer interface

Brain-computer interface is a direct connection between the computer and the human brain. This is one of the most recent developments in the Human-Computer Interface or HCI. Mouse, keyboard or other input device is used to provide some input to the computer. but it is possible to input the computer directly from the brain at BCI. You don’t have to write anything, just bring it to the head, and everything on the screen will be typed. even with the mouse, you can move the mouse cursor. BCI has thousands of possibilities and applications. Everything possible between humans and computers can be done by upgrading this technology.

Think about Next Generation Gaming, where you don’t have to game from any keyboard or console. The head may have a wireless chip attached to it. and it will be connected directly to the computer. controlling the game from the direct brain. Think again about patients with disabilities who don’t hear. or don’t see. They can create and send electronic signals directly from the camera and mic to the brain for viewing and listening to them – tell us what could be greater discovery on the human-computer interface?

Moreover, more details about the brain’s activities and neural network will be revealed through BCI, which will enable further improvements and accuracy in artificial neural networks and mind-uploading technologies. Conona can make the computer more like we know the human brain.

Think about it, a social media post where you can post your photos, your memories, memories, and photos after uploading photos and others will feel the same way. In this way, as we begin to understand the brain more and more. the application can be improved. The BCI application system works on a complete brain operation. The input and output of BCI are discussed below.

The basic idea of ​​making this technology work properly has left many researchers in trouble because our brain is not such a simple thing, it contains cortical neurons and generates cortical signals all the time.

The human brain works in the most complex manner. To read the signal from the brain, it is necessary to put something on the head that captures the signals and sends them to the computer. For this purpose, electrodes are used. the device name is Electroencephalograph. And it needs to be applied to the skin of the head. The electrodes can read the electrical signals in the brain, but the problem is that many weak signals come from the brain and most of the signals block the skull.

Therefore, to get better signal quality. the researchers burst the skull and plant the electrode directly on the gill. [Click here to view the real picture of the electrode planted on the brain (1) (Figure 1 | Image 2). Poor: Pictures of weak-hearted people will be recommanded] By installing electrodes directly on the brain’s surface. the signal quality is much better than ever.

By the way, it is not a matter of having four electrodes placed on the very top floor of the gill with a burst of skull. which requires huge surgery. Once successful surgery is possible. the electrodes begin to capture the electrical signals from the brain since the signals are very weak so the signals are filtered and amplified to work properly. The pattern of these electronic signals is saved through a computer program. just like the audio waveform to see these signal patterns.

The signals are first read in a brain for some purpose, and then the actual reverse signals are generated from the BCI program on the computer and then planted in the neuron of the brain. Suppose your eyes are looking at some object. it must have some kind of signal approaching the brain. understanding the pattern of that signal. after taking a picture from the camera can be made to the same signal and planted in a neuron. but of course, the brain can see it. the visual image will be created in the brain.


Brain-computer interface As I said earlier. the possibility of BCI is not over. A lot of your imagination can be shaped into reality. However, after reading a lot of articles in this regard. I found that this technology is mainly being developed to help the handicapped, although there is much more that can be done. Yet there can be no greater purpose than this. With the camera, it is possible to give back sight energy to the blind. Moreover, this technology will be a blessing for those who have lost their hands or feet due to various accidents. They can be fitted with robotic hands and feet. which will work by receiving signals from the brain. but those whose robotic organs are implanted will need practice to function properly.

Besides, it would also be possible to move a computer cursor by thinking of moving an object in the brain, everything will become mind control. Moreover. it is possible to read the brain in more detail, maybe using the Mind to type something. and there will be the benefit of changing the TV channel without doing anything. It is important to note that once all the processes are done properly, there is no limit to the possibility of a brain-computer interface.

How far are we from BCI?

Having understood all the basics about the brain-computer interface by now, the most important question is now; Brain-computer interface How far is it before our eyesight technology? See the brain-computer interface is no longer science fiction, it’s living science! But it has not yet been possible to make the BCI perfect.

See, our brain is not that simple. our complex is more complex than any other complex machine in the world; It contains billions of neurons that continuously send and receive electric signals with each other. and the electrode has not yet been able to capture the signals so precisely. Moreover, not only the electrical signals in the brain but also the chemical matter there, it is impossible to capture by electrodes.

Moreover, a lot of weaker signals come from the brain. which is like capturing a story with someone standing ten feet away in the fish market. And the biggest problem is that the cable is still used on the Brain-Computer interface. as well as the size of computers. if the portable and wireless technology can be integrated here, then this technology will expand. But I’m sure we can.

The last word

Where it talks about something so extraordinary, it does not intend to pull it off. Even then, the article has to be very long because of this. So what do you think about such amazing technology? -What is the possibility? Can it be improved at all? – Tell us everything below.
