Sleep is essential to function properly. The brain needs sleep as well in order to function as well. In this study, research has suggested that during sleep, the fluid volume in the brain increases and helps flush waste products out that can precipitate disease. Fluctuations in the extracellular ion composition control these crucial volume changes. When manipulation of the ion mix occurs, mice in the study either woke up or dozed off. Previous research has also tied the flow of brain fluid to sleep and disease. To read more, click here.
