Have you ever wondered how your dreams appeared? Otherwise, you might have heard whispers of a theory suggesting that each dream is a reflection of an alternate version of yourself living in another universe. Imagine you can capture your dreams and explore every secret of your dream, sounds fictional! Well, a group of Japanese researchers have created a machine that can exactly do that fictional thing: record human dreams.
A group of Japanese researchers invented a device in recent years at the ATR Computational Neuroscience Laboratories in Kyoto, Japan, to unlock the mystery of human dreams by using functional magnetic resonance imagining (fMRI).
Machine to capture human dreams
Human dreams are the most complicated and mysterious factors. However, science has taken a step forward to explore the mystery of dreams. Japanese researchers at the ATR Computational Neuroscience Laboratories in Kyoto have constructed a cutting-edge machine that can record and play back dreams. The advancement of brain imagining and artificial intelligence (AI) have been used in this machine to make it powerful.
Professor Yukiyasu Kamitani led a research team and employed functional magnetic resonance imagining (fMRI) in their research. This has helped them to observe and record detailed neural activities in the brain associated with dreams. The study captures the cognitive activities of volunteers during the early stage of sleeping. So, what do you think how much accuracy it contains?
When the volunteers entered REM sleep- the stage of sleep associated with vivid dreaming- they were awakened and questioned about their dreams in detail like what they had seen. This process was then performed by the researchers again and again to gain a comprehensive database of brain patterns during sleeping.
The researchers analyse the brain scans and create a comprehending database of images linked to different brain patterns related to human dreams. They gain a remarkable 60% accuracy in predicting the dream content. The accuracy even increased to 70% for certain visual items like people and objects.
Professor Kamitani said, “We were able to reveal dream content from brain activity during sleep, which was consistent with the subjects’ verbal reports.” The device provides invaluable insights into human dreams. It has also explored the working patterns of the human brain, the nature of consciousness and the importance of dreaming.
However, it is necessary to keep in mind that the technology is in its early stages. More research needs to be conducted to ensure the accuracy of the dream recordings. When more research happens then the method of decoding dream content will be refined.
Ethical implication
Recording dreams might be a fascinating factor but there are some ethical concerns too. Recording someone’s dreams might cause the privacy issue. Dreams are completely personal experiences and several sensitive thoughts and feelings have been found in dreams. Henceforth, decoding them might lead to sensitive data breaches.
Until more research is conducted, there might be a chance of misinterpretations while using dream-recording machines. If misinformation got recorded in dreams it might lead to a negative impact on the volunteer’s personality.
Another ethical concern might be the misuse of the recorded information. Recording the dream of a governmental figure might be misused by malicious people for manipulation, blackmail, or political gain. It can also disrupt the mental space of people.
How does the dream appear
Human dreams are thoughts, sensations, images or feelings that appear during sleep. However, it remains a question for decades why do people dream? Well, different experts have different opinions about it.
Most of the dreams appear in rapid eye movement (REP) sleep. It is characterised by brainwave activities similar to consciousness. The forebrain creates dreams while the brainstem creates REM sleep. Any kind of injury in the part of the brain can disrupt the REM sleep or dreaming process.
Human dreams are strange. But why? Because it is mostly influenced by neurotransmitters in the brain during REM sleep. During the stage of REM sleep, the acetylcholine and dopamine levels in the brain increase. This helps in maintaining brain activation and contributes to the surreal quality of dreams. At the same time, chemicals that help us to stay awake get lowered and make the dreams feel even weirder.
But do you know how much time the dream lasts? Well, if we take scientific data we can find that dreams usually last for a few seconds or around 20 to 30 minutes. However, some people find that their dreams last much longer than they usually are. In this case, the dream-recording machine might be helpful to predict how much time the dreams last.
Significance of dream-recording machine in neuroscience
The invention of the dream-recording machine to record human dreams might contribute significantly to exploring brain activity during sleep and its connection with consciousness. A recent development in the neuroscience departments has been found in the development of AI in decoding brain signals.
The neuroscience department also gets advanced because of the development of fMRI and electroencephalography (EEG). These developments ensure more preciseness in brainwave tracking. The employment of fMRI in the dream-recording machine, henceforth, enhances the preciseness of recording dreams by around 60%.
The development of the machine by Japanese researchers can also help cure mental health issues. A new perspective regarding dreaming content and consciousness and unconsciousness level in the human brain can be explored with the new development of researchers.
Cultural believes regarding dreams in Japan
The Japanese cultural beliefs regarding dreams have evolved over centuries and have been influenced by the religious, societal and philosophical aspects. The Japanese people believed that if you can’t sleep at night then you might be awake in someone else’s dreams. The Japanese people believed that human dreams are connected to the spiritual world.
However, during the Samurai era of Japan, dreams were sometimes viewed as guidance. The Samurai of that period nurtured mindfulness thinking, but still used dreams as their guidance because of the Japanese beliefs that dreams are connected to spiritual importance.
