The Russians have put forward a new hypothesis of the origin of dreams


Institute of information transmission problems of RAS Ivan Pigarev offered his explanation for the fact that, falling asleep, sometimes people see dreams. Unlike most of the hypotheses that exist today, the new assumption does not imply that dreams have a certain useful function.

A Russian specialist argues that the awake human cortex for processing received signals from sensitive formations called “exteroretseptora”. After that, the information about the external razdelitel, according to pigareva, enters the structure of the basal ganglia, located in the area of the front of the brain, which leads to the formation in the mind of sensory images.

During sleep information from the “outside” man comes much less, therefore, most of them coming from “inside”, i.e. from the nerve endings, called intereception and located in the internal organs. In combination with a number of external signals is still perceived by a person, it makes the neurons of the basal ganglia to create images that are dreams. Thus, dreams according to the assumption of the scientist, are a kind of “noise” that have no functional value.

According to one prevalent alternative theories proposed by Sigmund Freud, dreams represent the hidden aspirations and suppressed desires of a person. There are also assumptions, according to which through the images that come during sleep, the brain “sistematizirovat” and processing the day impressions, “rehearsing” certain situations (especially potentially hazardous), or looking for a way to get rid of negative feelings.

Recently, a group of researchers from the University of Arizona, came to the conclusion that lack of sleep on weekdays, followed by attempts to “sleep it off” at the weekend, could be harmful to humans.
