Contact: [email protected] For centuries, it was believed that sleep is a state close to death, and brain activity basically dies. – It was not until 100 years ago that it turned out to be untrue – says Dr. Małgorzata Hołda from the Sleep Psychology Laboratory at the Jagiellonian University on the Scientific Radio. *Preparing each episode takes many hours of work. If you liked this podcast – you can support me on Patronite. Thanks! https://patronite.pl/radionaukowe * A breakthrough in sleep research was the creation of the electroencephalogram (EEG), thanks to which electrical activity of the brain began to be recorded. – In the 1920s and 1930s, it was realized that this activity during sleep exists, and is even completely different than during wakefulness – adds the researcher. And what about dreams? Is there one specific center in our brain that is responsible for dreams? – We do not know exactly, although it seems that there is no such center – says Dr. Hołda, and immediately adds that research on dreams is difficult. - We could use, for example, resonance imaging for brain imaging, but... it's hard to sleep in it because there's a terrible noise - she notes. That's why many studies are based on the test subjects' declarations. So we don't know, for example, whether women and men have significantly different dreams, or maybe they talk about them differently. Why do we dream at all? There are many ideas for explaining this phenomenon. - The Freudian ones have not been proven - Dr. Hołda immediately points out. A currently popular concept is the evolutionary explanation. Dreams are supposed to be a simulation of reality. Because our brain evolved in a dangerous environment, dreaming about threats is supposed to have adaptive significance. - The theory assumes that such dreams serve to practice reacting to various threats - says Dr. Hołda. Another idea indicates a function that organizes the events we have experienced. It is also possible that dreams are simply a byproduct of neuronal activity. - Something similar to the sound of a heartbeat - the researcher compares. Consciousness returns, the room is dark, you can hear the sounds of the night, and you... can't even move. People who have had such an experience describe it as terrifying. Especially since sometimes reality mixes with dreams, and the body doesn't move. This phenomenon is called sleep paralysis. - A disorder that in most cases does not indicate anything dangerous. The phenomenon consists in waking up from the REM phase. Our muscles in this phase are completely paralyzed, which is most likely to protect us from harming ourselves when we run away from something in the dream - says Dr. Hołda. It is in the REM phase that our dreams are the most intense. - It happens that consciousness returns too early, and the muscle atonia has not yet subsided - explains the scientist. In the podcast, we also talk about so-called lucid dreaming, whether we all dream, how to explain erotic dreams, what infants can dream about and what research tools sleep researchers would dream of. The idea for the podcast topic came from Ms. Magdalena, one of the patrons of Radio Naukowe on the patronite.pl/radionaukowe website.
