Molecules, nerve cells in brain trigger sneezes

A tickle in the nose can help trigger a sneeze, expelling irritants and disease-causing pathogens. But the cellular pathways that control the sneeze reflex go far beyond the sinuses and have been poorly understood. Now, a ...

Find relief for achy hands and wrists

Peripheral nerves connect your brain and spinal cord to the rest of your body. The peripheral nerves in your arms and hands allow you to move and to feel.

Alzheimer's disease & dementia

What happens in brain cells affected by Alzheimer's disease?

Affecting over 50 million people, Alzheimer's disease is the most common form of dementia and primarily occurs in people over the age of 65. The pathology of the disease in the brain is mainly characterized by two factors: ...

Neurocables to repair nervous system injuries

As the CBIT-UPV team explains, there is currently no effective clinical therapy for the regeneration of nerve injuries on nerve lengths greater than 2 cm, where the nerve cannot find its target and, often, that disoriented ...

Nerve

A nerve is an enclosed, cable-like bundle of peripheral axons (the long, slender projections of neurons). A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons. Nerves are found only in the peripheral nervous system. In the central nervous system, the analogous structures are known as tracts. Neurons are sometimes called nerve cells, though this term is technically inaccurate since many neurons do not form nerves, and nerves also include non-neuronal Schwann cells that coat the axons in myelin.
