Astrocytes or astroglia, the largest glial cell population in the central nervous system (CNS), perform numerous vital functions. Among other things, these glial cells (i.e., cells supporting functions of the nervous system) ...
Intriguing new research has pinpointed a special population of T cells—tissue-resident memory T cells—as key players in the development of chronic autoimmune disorders that affect the central nervous system, opening a ...
In mice, cognitive decline is influenced by obesity due to the potential association of an adipose-brain axis. To examine this proposal, Núria Olivera-Canellas, and a team of researchers in the departments of medicine and ...
The concept of new bone formation via divalent cations is widely reported although the underlying mechanism of the process remains unclear. In a new report now published in Nature Communications, Wei Qiao and a team of scientists ...
Neurons in the brain and spinal cord don't grow back after injury, unlike those in the rest of the body. Cut your finger, and you'll probably be back to using it in days or weeks; slice through your spinal cord, and you likely ...

(Medical Xpress)—Myelin is an electrically insulating layer, or sheath, made of protein and fatty molecules, and synthesized by cholesterol-rich oligodendrocytes, that forms around neurons and allows electrical impulses ...
(Medical Xpress)—Cranial irradiation saves the lives of brain cancer patients. It slows cancer progression and increases survival rates. Unfortunately, patients who undergo cranial irradiation often develop problems with ...
Johns Hopkins scientists say they have evidence from animal studies that a type of central nervous system cell other than motor neurons plays a fundamental role in the development of amyotrophic lateral sclerosis (ALS), a ...

The central nervous system (CNS) is the part of the nervous system that functions to coordinate the activity of all parts of the bodies of multicellular organisms. In vertebrates, the central nervous system is enclosed in the meninges. It contains the majority of the nervous system and consists of the brain and the spinal cord. Together with the peripheral nervous system it has a fundamental role in the control of behavior. The CNS is contained within the dorsal cavity, with the brain in the cranial cavity and the spinal cord in the spinal cavity. The brain is protected by the skull, while the spinal cord is protected by the vertebrae.
