The Role of Locus Coeruleus in Sleep Quality and Memory

The locus coeruleus, a small brain nucleus responsible for managing noradrenaline, has been found to play a crucial role in regulating REM sleep and its impact on cognitive processes such as memory and emotions. Advanced MRI studies have revealed a correlation between locus coeruleus activity during wakefulness and REM sleep quality, particularly in individuals aged 50-70. These findings could provide insights into sleep disorders and their connection to conditions like Alzheimer's disease.
