The Human Brain has always been an enigma for scientists due to its complex nature. However, the human brain is known to emit electrical impulses called brain waves, which can be measured using an electroencephalogram (EEG). Recently, a new device called “the crown” was developed, which is a compact and stylish electroencephalogram that can be worn on the head. It uses tiny electrodes to measure brain waves, and it can connect to a mobile app via Bluetooth or Wi-Fi. The app not only provides helpful utilities like how to improve focus but also streams the brain’s data into the ether. The crown device has a price tag of about one thousand dollars.



Communicating with GPT-4 using nothing but your thoughts may seem like a scene from a science fiction movie, but with the latest advancements in technology, it is slowly becoming a reality.


Scientists have recently been able to connect our brain to GPT-4 using a futuristic device called The Crown.




What’s interesting about this device is that it has a JavaScript SDK that allows users to hack into their own brain waves. With the crown, it is possible to communicate with GPT4 using nothing but thoughts. This opens up possibilities for a transhuman cyborg future where every human being, or at least every rich human being, will have all the knowledge in the world at their fingertips, or rather at their brain tips.


The Crown is a compact and stylish electroencephalogram (EEG) that can be worn on the back of your head. The device consists of tiny electrodes that measure your brain waves and connect to a mobile app via Bluetooth or Wi-Fi. The app provides helpful utilities, such as how to improve focus, but the host of the video was more interested in accessing the raw data, which could easily be obtained in JSON format through the device's JavaScript SDK.



Brain waves are measurable electrical impulses emitted by the human brain. Scientists have been measuring these waves for decades using electroencephalograms or EEGs, which connect electrodes to your head. The host of the video was able to get his hands on The Crown, which is a futuristic device that uses the same basic idea as Elon Musk's Neuralink, without having to drill a hole into your skull.

When you're asleep, your brain emits low-frequency delta waves around 2 Hertz. These waves increase in frequency when you're awake and relaxed, becoming alpha waves around 10 Hertz. When you become highly focused, such as when solving a coding problem or playing chess, they increase to 35 Hertz, and these are gamma waves, which are useful for actually controlling things. Brainwave patterns are highly dynamic and can rapidly change depending on a person's cognitive state, mental processes, and external stimuli.


However, Neurosity, the company that makes The Crown, provides a dashboard where you can train algorithms to recognize your own custom thought patterns. For example, the host of the video trained the device to recognize when he was thinking about biting into a lemon. He did this by imagining biting into a sour lemon and then relaxing when the device prompted him to. After doing this about 30 times, the device learned to recognize that thought pattern. When he stopped thinking about biting into a lemon, the chart did not move, but as soon as he started thinking about it again, the chart went wild.


But how does this work? Brainwave patterns are highly dynamic and can rapidly change depending on a person’s cognitive state, mental processes, and external stimuli. When we are asleep, our brain emits low-frequency delta waves around 2 Hertz. When we are awake and relaxed, these waves increase their frequency, becoming alpha waves around 10 Hertz. And when we become highly focused, like when solving a coding problem or playing chess, they increase to 35 Hertz, and these are gamma waves, which are useful for actually controlling things.

The Crown provides a dashboard where algorithms can be trained to recognize custom thought patterns. For example, you can train the algorithm to recognize when you are thinking about biting into a lemon, by repeatedly imagining biting into a sour lemon and then relaxing when it tells you to. After doing this about 30 times, the algorithm will learn how to recognize that thought pattern. So, when you think about biting into a lemon, the chart goes wild, and this is accurate to the point of being somewhat frightening.

While it is time-consuming to train the algorithm to recognize different thought patterns, it is worth it as it opens up many possibilities. With this technology, people can use their brainwaves to control things like prosthetic limbs, cars, and even houses. However, this technology also raises some concerns. If it becomes possible to control things using just our brain waves, it could become dangerous if someone else gains control of our brainwaves.

In conclusion, the Crown device is a groundbreaking technology that allows us to communicate with machines using nothing but our thoughts. While this technology has a lot of potential, it also raises concerns about privacy and security. With further research and development, this technology can revolutionize the way we interact with machines, making life more comfortable and efficient.
