How the waste gets ‘Washed Out’ from Brain themselves during the sleep?

There has been a new study on the human brain. In this study, it seems that the waste inside our brain is washed out while we are sleeping. This happens because of cerebrospinal fluid. The waves of the cerebrospinal fluid washed out the waste inside our brain. This helps in clearing any useless material that is inside our brain. Recently, medical studies show that the Immune cells are highly active when we sleep. These immune cells are busy working in cleaning while we are sleeping. Studies also show that sleep very important for our brain and body. It is not only an important form allowing our brain to rest but also for cleaning the waste inside our brain.

The Process

A lot of complex work goes on inside our brain when we sleep. But, we are not fully aware of how this exactly happens. Previously we only knew that sleeping is important so that our brain can rest. But, now, the researchers of Boston University of Massachusetts are successful in finding out more. Their studies show that the main component is cerebrospinal fluid. This fluid is present in the spinal cord and brain. The accumulated waste material is washed out by the waves of this fluid. The co-author Laura Lewis says, “we also knew that there is an activity of electronic waves inside the brain. But, now we also know that there are waves in the cerebrospinal fluid too.”

The study became successful after they kept 13 volunteers under observation. These volunteers were people ranging from 23-33 years old. The volunteers were willing to let the researchers examine their brains while they are sleeping. But, this was not at all an easy task. The volunteers needed to wear ECG caps on their heads. These caps were important for measuring the change in the electrical activities of the brain. But, not only this, but they also were sleeping inside an MRI machine wearing these caps. But, sleeping inside this machine was a tough job as the machine makes a lot of noise. Despite all these drawbacks, the researchers were able to monitor brain activity properly.
