Invasive brain reading tech. One type measures electrical activity on the scalp. In medicine, they use e g caps for this, but sleeker looking wearables are available to. You only have to think and the lamp dims the light and the video begins to play all thanks to this wearable. The head band is a non invasive brain computer interface or b, c i. It was developed by a neurotechnology stud up from france, senses in the head band read brainwaves and translate them into commands for Electronic Devices. B, c, i is like this could be game changes for video games. They could enhance or even replace controllers allowing full greater speed and more intuitive game play. Being able to control devices with thought is especially useful for situations when you need your hands for other purposes. A kid like this costs around 400. 00 us dollars. These headphones from a u. S. Start up claim they can tell their wearer when they focus best to help them work more efficiently. The electrodes which measure the brain waves are located in the headphone padding. Electric activity in the brain indicates concentration levels. The measured data is processed in an app to show whereas when they are able to work most productively music to fit your current mood and alerts for when you need a break are also included this b. C, i should become available for purchase in 2022. For some a brain computer interface would be nice to have. But for others it would drastically improve their quality of life. Like for people who are paralyzed, a successful brain implant would increase their independence. This dream has come true for Nathan Copeland. Here we see him playing the game final fantasy just by thinking. And here is his robot hand in action. This is how his brain computer interface works. When Nathan Copeland suffered an accident in 2004, he was left with tetra peach at paralysis. But thanks to a brain computer interface, nathan can now move a prosthetic arm. Electrodes in his brain, read his brain waves and sent signals to move the prosthesis. The reason why we are able to control Electronic Devices by the power of thought alone is because our brains use electronic signals. Ah. The human brain has 86000000000. 00 neurons, and each one sends signals across thousands of synopses. When we want to raise our arm, say, a region in our brain becomes active as neurons fire. If the voltage changes by a large enough amount, over a short interval, a neuron generates an all or nothing electrochemical pulse called an action potential, and a signal gets sent between the neurons. This action potential can be measured with electrodes. These have miniature metal needles that record the voltage change. The more needles in electrode has the more accurate the measurement. Nathan copeland had an operation to insert force such electrodes into his brain to were implanted into his motor cortex, which controls movement and to into his amount of sensory cortex were Sensory Perception is processed thanks to these electrodes. Nathan copeland can now control movements when hes connected to a computer. To achieve this, however, both sides had to 1st learn to understand each other. The computer needed to learn to read nathans brain waves and translate these into the correct movement. To achieve this, nathan watched videos of movements he wanted to make. Meanwhile, the b. C, i measured the action potentials in his motor cortex. While nascent copeland was concentrating on the movement, the computer recorded the action potentials and compared them using Artificial Intelligence and Machine Learning algorithms. Now when nathan thinks a specific movement, the computer recognizes it and moves the prosthesis accordingly through the 2 other chips in his sematic sensory cortex. He is also able to feel with his prosthesis i brain computer interface. Research has come a long way. Take the example of neuro grains. These microchips are each about the size of a grain of salt and have been designed to be scattered across the brain surface or inside its tissue. Their advantage is that they can detect and pass on signals from many areas of the brain. A team at Brown University in the us develop the system. And there are many other projects. The australian company, syncron has succeeded in getting a brain computer interface into the brain through blood vessels. Thus avoiding the need for brain surgery. The 1st person to be implanted with his stent rod interface is the australian graeme fell stead, who suffers from a l. S. And nervous system disease, which progressively paralyzes the body. His brain signals are transmitted to a sensor in the chest where we receive a forward them to a computer. This enables graeme fell state to chat and surf the internet using thought alone. Here is subject imagines writing letters by hand and brain. Computer interface transforms them into time to letters on the monitor. The accuracy is 94 percent. It is considerably faster than previous systems where subjects would have to mentally choose letters on a keyboard. These brain computer interfaces were developed by Stanford University in the u. S. Ah, previously robotic alms werent able to have such fluid and natural movements. This new non invasive brain computer interface was developed by researchers at the courts university. As the technology improves, e g caps could become a future alternative to implanted chips. Ah, using e g caps instead of brain surgery is definitely less risky. Because implanting electrodes directly into the brain can cause bleeding or scarring, or the electrodes could be reject it. And if they need to be taken out at a later point, that could also lead to complications. But beyond the physical risk of brain computer interfaces, experts worry there are other serious dangers. What would it mean if we were in full control of our minds . All same is addiction, depression. Those could all become a thing of the past. But so could traits that make us human . Transact osman twist. I would say our traits can be altered by deep brain stimulation and on come as a brush, for example, or someone who was shy, can suddenly become extroverted at yet spend more money target or change their sexual behavior. But i found that sense ex wife a hide. Now this is already been observed for laughter. And it leads to the question of how important these traits are, ang shaft, and how much they belong to Something Like our core selves. When, if something is an essential part of us analysis vaskins, then we probably want to protect it this and will remain in the shouldnt to wire. One person who believes in technologys potential is ellen musk every less encoded in memory. You could, you could upload, you could basically store your memories as a backup and restore the memories. So if you could potentially download them into a new body or into a robot body, a future is going to be where many new role edges do not buy into ill on masks, vision of brain backups. The scans, the guy whos saving the contents of the entire brain on a hot disk would mean covering both sides of the brain. So the entire brain with electrodes and also copying the interactions between the billions of neurons accurately yall, thats i think that technically and physically this is not possible. Whos calling miss motto. And then there are also ethical questions to consider. Dish vilnash i would be vulnerable to anyone who has access to this data from my bank details to my deepest secrets. The idea that big tech could know my private thoughts is really scary to me. But to be clear, there is currently no brain computer interface that can decode or thoughts. That mixture of images, sounds, smells, and words is hard to crack. We may soon have busy eyes that allow us to message up to 5 times faster by thinking the letters rather than typing them. Yet there are important ethical dimensions to Tech Companies developing the systems like google, which is also investing in b c, ies, these companies have not always protected their users. And what if, at some point we are pressure to linking our minds to computers . Like we are pressure to being on social media. What if any rich and privileged people get access to this technology . Or is powerful figures like even lusk, increase social pressure to join this trend . Those without b, c, ies, would be left behind, defense the mass. Now am i give insights from clang house and once these measures become available outside of the clinical context and then pressure to use them will probably increase off on that. Oh, i see this monkey can man and um, but i, weve seen this in other areas such as beauty or sport where people feel pressured to reach certain standards because thats this then miss and the island with ma. Hm. This technology also lends itself to other uses like military purposes. The helmets shown in this film have electromagnets as used in e g. These are supposed to be able to control the brains of soldiers in the future in order to influence their anxiety or their aggression. What about pain . Can you start me feeling it . Us army laboratories have been intensively researching such applications since 2010 best of us doing also this is really happening. So its not a secret. Its Public Knowledge weaknesses on and our us colleagues have access to a giant Research Budget indian was all that leaves me with a bad feeling. Does 11 good new through experts believe that brain computer interfaces could provide a technical advantage and future wars by facilitating quicker decision making, better oversight and longer endurance. But how ethical would it be to manipulate people in this way and what, what the long term consequences b . If technology can help people were paralyzed, regain independence, then thats wonderful. That i worry about companies having access to my brain ways are thoughts and feelings are the most intimate data we have. So Data Protection is more important in this area than anywhere else. Whats your take on brain computer interfaces . What do you like to be able to message or play games using only your mind . Let us know wed love to hear from you. Bye bye and see as soon. Ah, i imagine how many portions of lunch us her now in the world right now. The climate change, if any hot story, this is my flex, the waste from just one week. How much work can really get we still have time to go. Im going all with what 1st . His subscriber all morning. He was like india. The land of contrasts. Of ambitions of inequality. 75 years ago, Mahatma Gandhi peacefully led the country to independence, full of ideals. What is remained of his vision . Whats this as of human rights and social justice in whats called the Worlds Largest democracy . Ah, we receive your head it. This is the pulpit tour unleash on,
