Bedtime is one of the most important parts of the day for the brain. The latest studies show that when we slumber, the brain performs important housekeeping tasks that clear away the debris of the day’s work and help reset and restore nerve networks so they are ready to operate again at full capacity when we wake.

But a lack of sleep deprives the brain of this essential rest period, and our ability to get through the day might be compromised. In a small study published in the journal Radiology, a team of Chinese and European researchers report a more detailed analysis of how insomnia can affect specific types of brain nerves in parts of the brain that regulate cognition, emotion and sensory processes.

The researchers compared the brain images of 23 people with insomnia and 30 healthy controls. They specifically focused on white matter volume, which represents nerve cells that are coated in a special protein called myelin that improves their ability to send signals to one another. Earlier brain imaging studies had suggested that people with insomnia have differences in certain parts of the brain that could be connected to inadequate myelin. So Shumei Li from the Guangdong No. 2 Provincial People’s Hospital and her colleagues compared white matter function among people with insomnia and those who slept well.
