The new experiment does not detect signs of dreams in brain waves

Science

In The Dreamcatcher night experiment, people’s dreams penetrate the web. If we only see the brain wave activity of humans who are sleeping, scientists cannot reliably understand the dreamer’s brain.

The details of the leaked network, explained at bioRxiv.org on May 27, have not been reviewed by other scientists. The results must be carefully considered because they contradict previous studies that described dream signs in neuronal data. Experimental design is important because scientists suspect that dreams contain secret traces of the deepest consciousness itself.

The brain can also make a rich curtain of awareness without detailed information. The study of brain-created awareness cases, which includes dreams, wandering thoughts and dreams “is a powerful method for understanding the relationship between the brain and mind,” said study co-author Naotsugu Tsuchiya of Monash University in Clayton, a city near Melbourne , Australia.

Zuchiya and colleagues analyzed data from nine people who slept overnight in the laboratory while wearing electrode caps used to measure brain waves. The researchers focused on the stage of sleep called non-REM sleep. (Dreams are so abundant in REM sleep that researchers will find it difficult to find enough examples of dreams to be used as comparisons.) To identify dreams, researchers use an annoying method: they wake people up after they turn into humans who have no dreams. -REM-sleep has occurred and asks if the man has a dream.

free from unwanted irregularities, the project relies on two teams of researchers, data collectors and data analysts to experiment. After the collector collects brain wave and dream data and unconsciousness, the data is transferred without guidance, whether the dream is also about Tsuchiya’s topic and other data analysts.

First, sophisticated analysis algorithms divide data into clean groups. “We are very confident that we succeeded,” Cuccia said. However, after the data collector reviewed the results, it became clear that the experiment could not rank the data into a pile of dreams and unimaginable. Even after the data collector explains which data comes from any object, the analyst is still not able to detect the signs of dreams that can include the types of brain waves emitted from certain locations in the brain, for example.

This error was not suitable in previous studies that had dreams about brain activity, including studies of nature in neuroscience Giulio Tononi and colleagues. The difference may be due to problems with the new study method, said Tonyny, a neuroscientist at the University of Wisconsin-Madison. Compared to a survey in 2017, this new experiment involved fewer objects, fewer electrodes on each person’s scalp, and used a longer period of time to determine the dreaming time that might include unintentional confusion, from dreams to unthinkable ones.

Luigi December dream researcher Zhenaro from Rome University Sapienza, who also dreamed of finding neuronal signatures, agreed that methodological problems might be responsible for the negative results of Dream Catcher.

Exploring what dreams reveal about consciousness is a rich but temporary field. Although Tononi is unsure of the results of the Dream Catcher trial, he said he was happy to see more studies of dreamer brains.
