Vagus nerve stimulation may treat many diseases by changing brain signals, inflammation, and organ communication.

A new study has found that during exercise, the vagus nerve, essential to the body’s ‘rest and digest’ response, has a more important role in heart function than we thought. The findings could be ...

A complex system of nerves and muscles enables the human eye to blink, gaze, and shift focus. The trochlear nerve is one of six cranial nerves that carry electrical impulses from the brain to the eye.

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 ...

The hypoglossal nerve is one of the 12 cranial nerves arising from the brain. It's a paired nerve, and you have two — left and right. Together, the two hypoglossal nerves control the muscles of the ...

The vagus nerve is a vine of nerve fibers with roots in nearly every organ and shoots in the brain. It helps us detect a racing heart, rising blood pressure, stomachache, discomfort, an overzealous ...

The retina is often referred to as an “outpost of the brain” – after all, important steps in visual signal processing do not take place in the cerebrum, but in the nerve cells in the eye. When light ...

In 1921, Otto Loewi woke from a dream with the idea for an experiment that proved nerves communicate using chemicals, not just electricity. By showing that stimulating one frog’s heart released a ...

Congenital aniridia is a rare disease caused, in most cases, by mutations in the PAX6 gene, which is essential for the development of ocular structures. Although the most visible feature is the total ...

Using microelectrodes, scientists could show that cells in the retina play different roles. The produce different signals, which is important for the processing of visual information. These ...
