Brain-computer interface

If you imagine the future of technology, what kind of imagination will come to your mind? – Changing the TV channel without doing anything (not even remotely)? Play computer games with the help of mind Or keep the game straight in the head without playing the game on the monitor? Growing up in the computer game world? People’s minds dropped? Your imagination has seen on a computer screen? – While all these ideas are insane, it is possible to preoccupy them with brain-computer interfaces or BCI technology.

 

Modern computers are becoming more and more sophisticated as they try to understand the human brain. And as a result, we can turn our fantasy science fiction into a busy one. In this article, we will learn how BCI works and discuss the feasibility of this technique, so let’s start …

 

Brain electrical signal

Why do we compare the human brain and computer and why do we want to combine 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, is made up of billions of tiny cells called neurons, each nerve cell connected by dendrites and axons.

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

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

And the data is zipped between the signals your eyes see. Now if you can read that signal and send the same signal directly from the camera and send it directly to the brain, then your brain will see the same color, thus it will be possible for the camera to make the signal back blind. Because no matter how large the eyes of the blind are, their ability to recognize signals in the brain is not 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. A mouse, keyboard, or other input device is used to provide some input to the computer, but it is possible to input directly from the computer to the BCI. You don’t have to type anything, just bring it to the head, and everything will be typed on the screen, even with the mouse you can move the mouse cursor. BCI has thousands of possibilities and applications. By upgrading this technology, every effort can be made between humans and computers. Think about next-generation gaming, where you don’t need to be gaming with any keyboard or console. The head may have a wireless chip and will be directly connected to the computer, controlling the game directly from the brain. Think again about patients with disabilities who do not hear, or do not see. They can create and send electronic signals directly from the camera and mic for them to see and hear – tell us what else it could lead to on the human-computer interface?

Also, more details about brain movements and neural networks will be revealed through the BCI, which will enable further improvements and accuracy in artificial neural networks and mind-upload technologies. -Corona can make computers 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 the BCI are discussed below;

 

BCI input/output

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

The human brain works in the most complex way. To read signals from the brain, it is necessary to put something on the head that captures the signals and sends them to the computer. Electrodes are used for this purpose, the device is named electroencephalograph, And it needs to be applied on the skin of the scalp. Electrodes can read 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.

 

By the way, it is not a matter of placing four electrodes on the floor above the gill with a rupture of the skull, which requires major surgery. Once successful surgery is possible, the electrodes begin to capture electrical signals from the brain, as the signals are very weak so the signals are filtered and amplified to function properly. The patterns of these electronic signals are saved through a computer program, such as an audio waveform to visualize these signal patterns.

The signals are first to read into the brain for some purpose, and then the actual reverse signals are generated from the BCI program on the computer and then placed in the neuron of the brain. Suppose your eyes are looking at an object, then there must be some kind of signal near its brain, understanding the pattern of that signal, the same signal can be made and applied to the neuron after taking a picture with the camera. It is, but certainly, the brain can see it, a visual image will be created in the brain.

 

Brain Application

 

Application

Like I said earlier, the possibility of BCI is not over. Many of your imagination can be shaped into reality. However, after reading a lot of articles in this regard, I found that this technique is being developed primarily to help the disabled, although much more 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. Furthermore, this technique will be a blessing for those who have lost hands or feet due to various accidents. They can be fitted with the hands and feet of the robot, which will work by receiving signals from the brain, but whose robot organs are implanted will require practice to function properly.

Also, thinking about moving an object in the brain will make it possible to move the computer cursor, everything will become mind control. Also, it is possible to read the brain in more detail, perhaps using Mind to type something, and would have the benefit of changing the TV channel without doing anything. It is important to note that once all processes are performed 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 so far, the most important question is now; How far before our vision technology is the brain-computer interface? See the brain-computer interface is no longer science fiction, it’s a living science! But it has not yet been possible to make the BCI perfect.

See, our brain is not as simple, our complex is more complex than any other complex machine in the world; It consists of billions of neurons that continuously send and receive electrical signals with each other, and electrodes have not yet been able to properly capture the signals. Furthermore, not only electrical signals in the brain but also chemical substances, are impossible to capture by electrodes.

Also, lots of weak signals coming from the brain, which is like capturing the 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 portable and wireless technology can be integrated here, it will be an extension of the technology. But I am sure we can.

 

Final word

Where it talks about something extraordinary, it does not intend to end it. Nevertheless, because of this, the article needs to be very long. So what do you think about such amazing technology? -what are the chances? Can this be corrected at all? – Tell us everything below.
