University of Lausanne Nov 25 2024 Researchers at the University of Lausanne have identified a novel role for the brain's 'locus coeruleus' in sleep and its disruptions. This brain region facilitates the transition between NREM and REM sleep states while maintaining an unconscious vigilance toward the external world. Stress disrupts its functions and negatively impacts on sleep quality. Sleep disorders affect an increasing number of people, with potentially serious consequences for their health.
