Finding the cells that put our brain to sleep

Researchers have identified a type of rare cell in the brain that plays a significant role in regulating sleep. These cells, known as vaso vasorum cells, have a unique characteristic - they have widespread connectivity, meaning they are connected to a large number of other cells in the brain. Studies have shown that these cells are more likely to be active in individuals who are in a state of deep sleep. When these cells are activated, they send signals to other parts of the brain, which can trigger the onset of sleep. This discovery could lead to a better understanding of the mechanisms that control sleep and potentially inform the development of new treatments for sleep disorders.
