The process of scientifically recording dreams and showing them as movies the next day
We spend about a third of our lives sleeping.At some point in the past, did you ever think of such a question, if one day our science and technology developed, then we human beings may rely on a certain technology or some advanced instruments to record their dreams?And you can watch it again the next day like a movie.They can even control their dreams and change the direction of their dreams.Not to mention, there are actually scientists who claim to have mastered this technology.This is The Russian newspaper, which once reported on the technology of recording dreams.According to Vladimir, one of the scientists on the team, they started the project in 2019, initially with the aim of saving patients from strokes and other brain problems.When it comes to dreams, sleep is the first thing that comes to mind and one of the most important activities in our lives.The average person goes through about five different stages of sleep over a period of about 100 minutes.After the five stages are completed, the cycle moves on to the next one.The five stages are sleep, light sleep, deep sleep, and rapid eye movement.The scientists came to their conclusion based on a final analysis of brain waves observed during sleep.The first stage of sleep is what we call the period of time when we begin to fall asleep.At this point the human brain will feel groggy and slowly begin to lose consciousness.From the brain wave observation data, we can find that the frequency of brain waves at this time gradually slowed down, vibration amplitude also began to decrease.After a while, you enter a period of light sleep.Scientists have found that light sleep’s brain waves rise and fall, as well as big and small, with extremely erratic frequencies.During periods of deep sleep and deep sleep, brainwave data begin to slow down.The last stage is rapid eye movement.When a person enters rem, his brain waves change suddenly.The brain waves are roughly similar to those that occur when the body is awake.For some people it is accompanied by certain physical activities, such as turning over, grinding teeth, and pulling the quilt.At the same time in this stage of the human body, but also the most easy to wake up a stage.So scientists define this stage of sleep as being half awake and half asleep.And the dream we’re talking about today is the brain activity that occurs during REM.Vladimir said.Their current technology can’t reconstruct the dream, but they can easily analyze the data to see what kind of dream the participant is in.That is to say, dreams can be precisely categorized into multiple types.So at this point, we all have a question, what kind of scientific principle is the recording of dreams that scientists say is based on?Let’s find out.The most common way scientists record dreams is first with an MRI machine.While the subjects were asleep, the machine recorded their brain waves.1. It converts the brainwave data into binary data similar to the images.2. Then put these transformed data into the image database and let them automatically match to find those similar image data.So the scientists could get a picture of the subjects’ dreams.This is just the first round of information gathering.The scientists had pictures of the subjects’ dreams, but far from achieving what they expected, their plan was to get the subjects’ entire dreams, a continuous video picture.So the next step was to develop a new piece of software.The software can be linked to multiple short-video databases.All they have to do is feed that image data into the software, and it automatically matches.Find short videos that closely resemble the images.Finally, through artificial intelligence analysis and processing, a complete and more similar video picture can be obtained.This is the video of the subjects’ dreams.The whole experiment process, if analyzed from a theoretical point of view, seems to be really possible.But real scientists didn’t even get the first round of photo information right.However, another way to participate in brain activity and record dreams has become the focus of scientific attention in recent years.It’s Elon Musk’s brain-computer interface experiment.The technology is a chip that can be implanted in the brain.Chips implanted in the brain can stimulate and accurately record any brain activity.Even more incredibly, it can predict in advance what decisions the brain will make next.In April 2021, a brain-computer interface chip was successfully implanted into the brain of a monkey.The monkeys were able to control the game in front of them using their minds, without having the cord connected to the controller.Musk said in an interview.Their team will conduct many more experiments.To ensure the safety of the chip implantation and removal of the brain, and to keep the chip stable and normal operation throughout the experiment.And Musk plans to test brain-computer interfaces on human brains for the first time in 2022.Once brain-computer interface technology is mature, it means that the chip can be paired with our external phones and computers, so that we can easily access the dream data of the brain.To make it easier to create a video of our dreams.Maybe one day we’ll actually be able to project our own dreams onto our phone screens for us to watch.Well, that’s it for this episode.
