Scientists from Tafts University (USA) have established why people have strange dreams. According to their theory, thus the brain learns to cope with surprises, reports The Guardian.
The question is why we see dreams, has long caused a discussion in a scientific environment. There are no means to record dreams, so it is extremely difficult to establish what their items are and what they differ from different people.
The authors of the new scientific work relied on the mechanism of learning artificial intelligence. They noted that in certain situations there is a “oversaturation” of information: neural networks also remember the data loaded in them and act on the same scheme, to consider it ideal. To induce artificial intelligence to make new unaccounted actions, scientists make some chaos, distorting incoming data.
The authors suggested that the brain makes something similar when “forms” dreams. Most people live in the usual setting, when one day looks like another and nothing unexpected happens. But the brain must be kept in a tone and be able to respond to new circumstances.
When people are awake, the brain cannot distort the data, but in a dream the situation changes. Scientists concluded that the dreams with their strange paintings can make our understanding of the world less simplified and more comprehensive.
“It is the strangeness of dreams in their discrepancy with the experience of wakefulness gives them their biological function,” the study says.
