Close your eyes and imagine with me a pleasant drive through your favorite city. Suddenly, you come upon a section of town where bags of trash are piled one on top of the other, obviously for weeks, because they haven’t been picked up by the trash collectors. Actually, you could hardly believe they are bags because they are now just a complete mess. Now imagine the scavengers and wildlife crawling around, among, inside the mess, armies of flying bugs brought in by the odor brewing out of it. Not a pleasant thought, right? What if I could tell you that’s exactly what is happening within your own system?
The alcantarilla system in our brain is a well-functioning trash pickup and cleaning mechanism that would assure us peace of mind and a healthy body.
The Glymphatic System
Studies show that eight hours of sleep regularly is needed to excrete brain fluids containing toxic substances, and thus recover resilience and promote a healthier thinking and emotional stability.
Dr. Tara Swart explains that this process is carried out by the glymphatic system conformed by the glial cells in the central nervous system of the brain. In 2012, a team of researchers from the Universities of Rochester (United States) and Copenhagen (Denmark) revolutionized the field of neuroscience by discovering the glymphatic system, which functions as a drainage method used by the brain to eliminate waste products from the central nervous system, including beta-amyloid and tau proteins, which are harmful in excessive quantities.
Glia Cells
A group of cells known simply as glia or neuroglia consist of cells of the central nervous system that interact with neurons in increasingly surprising ways. Decades ago, when they were first identified, it was believed that they served only as support for neurons. But now it is known that glial cells can release neurotransmitters—molecules that regulate neuronal activity, such as glutamate and serotonin—overturning the idea that only neurons could release neurotransmitters. Recent studies have indicated that glial cells play an important role in pain transmission, primarily in neuropathic pain.
Generally round in shape, these cells do not have axons and are ten times more numerous than neurons which resemble stars in shape. When glia are active, they appear brighter and more reactive.
In some physiological processes, glial cells may be as important as, or even more important than, neurons. More comprehensive studies will be able to better clarify the effect of glia in the maintenance of pain processes.
Physiology
The glymphatic system is made up of water channels and uses cerebrospinal fluid (CSF) as its transport fluid. The CSF is clear and colorless, surrounding the brain and spinal cord. Its main function is to provide protection cushioning against impacts or injuries.
Brain Cleaning System
The glymphatic system, broadly speaking, involves the flow of interstitial fluid, facilitated by glial cells, and performs the same water drainage function in the brain just as the lymphatic system does in the rest of the body’s organs, facilitating the transport of solutes and waste products from the CSF.
It is a vascular system for waste removal in the brain—similar to the lymphatic system—transporting solutes and waste products from the cerebrospinal fluid and the extracellular fluid of the brain.
It is fascinating how the brain works. What a perfect piece of machinery it is! That perfection comes from our Creator.
