Scientists at the University of Toronto are closer to understanding what causes  rapid eye movement or REM  sleep disorder…a disease that causes people to act out their dreams while in deep sleep.

New research published in today’s  issue of The Journal of Neuroscience says two powerful brain chemical-systems work together to paralyze skeletal muscles during REM sleep.

 It was thought   only one chemical  caused this effect.

During REM sleep your eyes continue to move but the rest of the body’s  muscles motor neurons are stopped.

Study author John H. Peever says REM sleep disorder is often an early indicator of neuro-degenerative diseases, such as Parkinson’s in 80 percent of people who have it.

He says knowledge of the two chemicals effects could help in curing REM Sleep disorder and may help prevent or even stop its development.
