Scientists open their eyes while sleeping, revealing surprising brain activity
Although sleep is a moment when it comes to lowering electricity and replenishing our energy, our brains are still very active while we rest. In fact, according to a team of researchers, researchers who recently analyzed eye movements during sleeping periods said that the back of closed eyelids was more than we had previously thought.
In a study published Wednesday in the journal Nature Communications, Swiss researchers analyzed students from sleep participants. The study shows that our students keep changing sizes, and we unconsciously show that the brain’s activation levels are different, which is how the brain responds to stimuli. With further research, doctors may one day use student activities to diagnose conditions such as sleep disorders.
Student dynamics “reflect the level of brain activation in the arousal state or area responsible for sleep regulation,” says Caroline Lustenberger, a neuroscientist at Eth Zürich in Zurich and co-author of the study. “These observations contradict the previous assumption that the levels of arousal during sleep are very low.”
The nuclear zodiac (part of the brain that regulates activation levels) is located in the brain stem, and it is well known that it is difficult to study when an individual falls asleep, the researchers say. Because students are known to reflect brain activity, Lustenberger and her colleagues believe they can also be used to track brain activation during sleep.
The team claims to be the first person to watch eye movements for several hours in sleep at one time, and I know what you are thinking: how? The featured images in this article are not stock photos, it shows how they actually did it. The researchers simply put one eye of each participant on one eye, wet it with the ointment of the eye, and sealed it behind a transparent bandage.
“Our main concern is that the subjects will not be able to sleep with their eyes open. But in a dark room, most people forget that their eyes are still open and they are able to fall asleep.
Overall, participants’ student movement showed that activation levels were constantly changing during sleep. According to the researchers, this finding confirms the biological characteristics of humans recorded in rodents.
The team also noted the link between student dynamics during sleep and specific brain activity patterns, including brain waves related to sleep stability and memory consolidation. Furthermore, they found that the intensity of the brain’s response to sound depends on the activation level of the participants’ students. However, the study did not demonstrate whether the dinucleus of the locus directly affects student dynamics.
“We’re just looking at changes in students related to brain activation and cardiac activity levels,” Lustenberger explained. The team aims to study this potential dynamic and how activation levels affect sleep. If they do find a strong causal relationship, they may one day use student exercise to detect diseases such as insomnia and PTSD, or even the recovery of comatose patients.
We haven’t figured out whether the eyes are windows to the soul, but as the team’s research shows, they are certainly windows to the brain!
