Glial cells are an integral part of the human nervous system. They help support and nourish nerve cells, or neurons. Several types of glial cells exist. Glial cells are the “glue” of the nervous ...

Microscopic cross-section through a peripheral nerve bundle (dark blue), which contains hundreds of nerve fibers coated with Schwann cells. Numerous large fat cells (light blue) can be seen in the ...

Traumatic injury to the brain, spinal cord and optic nerve in the central nervous system (CNS) are the leading cause of disability and the second leading cause of death worldwide. CNS injuries often ...

Most people think of Alzheimer’s disease as an illness of aging. But in fact, the brain changes that characterize it begin ...

Resting brain stem cells hardly differ from normal astrocytes, which support the nerve cells in the brain. How can almost identical cells perform such different functions? The key lies in the ...

Researchers at Karolinska Institutet, have uncovered a previously unknown mechanism that helps pain sensing nerve cells stay ...

The recurrent laryngeal nerve (RLN) is critical for speech as it provides nerve function to muscles in the larynx, or voice box. People have two RLNs, one on each side of the neck. Instead of ...

Researchers demonstrate an artificial neuron made of conductive plastics that can perform advanced functions similar to those of biological nerve cells. “Mimicking the behaviour of biological neurons ...

No less than 16 different types of nerve cells have been identified by scientists in a new study on the human sense of touch. Comparisons between humans, mice and macaques show both similarities and ...

The nematode Caenorhabditis elegans has a simple nervous system consisting of just 302 neurones. The human brain, with approximately 90 billion neurones, is far more complex. Nevertheless, neurons in ...
