Japanese researchers have been able to detect the genetic factor associated with a sleep stage known for its intense nighttime dreams, and this medical discovery can help avoid a number of disorders in the future.
Researchers from the Rykin Center for Biomedical Research in Japan identified two genes that affect the so-called fast eye movement, according to the Scientific American site.
The sleep of rapid eye movement takes place during a limited period of the night and some medical circles describe this condition as disturbed by the disturbing dreams and physical movements.
People do not usually move during REM sleep, as the sleeper remains in a normal body, but in a state of disturbance, people may sound and make several movements.
The results showed that mice lacking the Chrm1 and Chrm3 genes slept less hours than other normal mice.
Japanese researcher Hiroki Yuda says this is the first time that science has come to genetic causes for the sleep of the fast eye movement, after this period has been a mystery for decades.
The study was carried out by focusing on neurotransmitters in rat brains and chemical reactions, and genetic engineering was used for the production of mice without genes associated with rapid eye movement sleep.
In the view of the academic U Haiashi, who did not participate in the study, that what has been revealed recently is very important, because it shows that sleep rapid eye movement is not necessary to live human, and has a comfortable sleep.
"The recent scientific findings help improve sleep, especially since rapid eye movement sleep often affects depression and other diseases in humans," said a medical researcher at Tsukuba University.
