Sleep May Not Be Controlled only by the Brain According to Research Led by Morehouse School of Medicine

ATLANTA, Aug. 8, 2017 /PRNewswire-USNewswire/ -- A recently released study from a team led by Morehouse School of Medicine shows that the process controlling sleep may not lie totally in the brain. Research published in the scientific journal eLife demonstrates that a circadian clock protein in the skeletal muscle, BMAL1, can regulate sleep amount and the ability to recover from lost sleep.

"We thought sleep was regulated by the main biological clock and other processes located primarily within the brain. Our findings are the first to show that an organ outside the brain, skeletal muscle, plays a significant role in the regulation of sleep, and changes the way we think about sleep regulation," said neurobiologist Christopher Ehlen, PhD., one of the team leads.

"This is also the first demonstration that circadian mechanisms outside the brain regulate sleep amount," said Dr. Ehlen. "If similar mechanisms are present in humans, this study could lead to a new potential target for the treatment of sleep disorders—skeletal muscle. It also suggests that the beneficial effects of exercise on sleep may be through skeletal muscle circadian clocks, and that the loss of skeletal muscle in aging, disease or space exploration may have a causal role in producing sleep disorders."

MSM researchers led the study and included scientists from the University of Florida and the University of Texas Southwestern and University of California Los Angeles. MSM's contributors included lead researcher Dr. Ketema Paul, Ph.D., Dr. Ehlen, Dr. Jason DeBruyne,Ph.D., Allison Brager,Ph.D, Cloe Gray, Ph.D., Julie Baggs, Ph.D., and Lennisha Pinckney, MPH.
