How Glial Cells Protect the Brain

While computers, cars, and smartphones are all immensely complicated devices, the most complex thing almost everyone interacts with on a daily basis is their own brain. Studies have found that human brains are extremely powerful computational tools, learn the facts here now and that they match and even sometimes exceed the world’s most advanced supercomputers in terms of their ability to process and represent information in an effective way. We have our brains to thank for our ability to conceptualize, visually perceive beautiful and complicated objects, plan and execute future plans, and many other higher order tasks that are inaccessible to most animals.

Given the immense value of the human brain, it makes sense that the vast majority of people care a great amount about keeping it healthy and functional. After all, my explanation is a life without a healthy brain is largely free of pleasures, no matter how luxurious or coddled it is. The problem is that a wide variety of different health problems can cause the gradual or sudden degradation of brain function. Alzheimer’s disease, mad cow disease, strokes, and nerve trauma can all compromise the brain’s ability to function properly or communicate with the body’s other infrastructures.

Thankfully, the human body has its own system of defense for its most important organ. One of these measures are the glial cells. Glial cells protect the brain by insulating the junctions of different nerves, making sure that their ability to communicate across different nerve endings is seamless and uninterrupted. This is important because the nerve system is what allows the brain to complete its computations, take in sensory stimulation, and send out orders to various body parts. When the glial cells protect the brain, they are really defending and preserving its ability to stay in constant communication with nerves that stretch across the body.
