Although neurons are considered the basic units of the brain and nervous system, they do not do all the work. Glia are a non-neuronal category of cells that do not transmit electrical signals but ...

Each year, according to the National Institutes of Health (NIH), millions of people in the U.S. are affected by spinal cord ...

Immune cells may forego an attack on the cancer and protect it instead. By communicating with these body systems, the cancer bends them to its own ends. Until recently, the nervous system was not ...

In 1898, Camillo Golgi, an eminent Italian physician and pathologist, published a landmark paper on the structure of “nervous cells.” In addition to the organelle that still bears his name, the Golgi ...

An electrical impulse cannot directly cross the gap so a different mechanism has to be used. Between impulses the transmitter molecules are rapidly removed from the synaptic cleft to prevent ...

Researchers devised a process to convert a skin cell directly into a neuron, eliminating the need to generate induced pluripotent stem cells. Such neurons could be used to treat spinal cord injuries ...

Gene therapy in the central nervous system (CNS) is hindered by the presence of the blood–brain barrier, which restricts access of serum constituents and peripheral cells to the brain parenchyma.
