As the wedding day draws closer, both men and women typically experience a case of nerves and typically are told this phenomenon goes with the territory and is completely normal, however, a new study has shown that those who experience these pre-wedding doubts, especially women, are more likely to get divorced within 5 years.

Typically, patients with a damaged nerve suffer from acute attacks of vertigo accompanied by nausea/vomiting, inability to maintain posture and horizontal nystagmus. (wikipedia.org)

However, when they began conducting their tests, they soon found out that it enabled nerve cell membranes to pull in more cholesterol, which in turn increased the vesicles that packaged neurotransmitters. (naturalnews.com)
Here, incoming signals effect the release of transmitters from stores known as 'vesicles', which fuse with the adjoining cell membranes in order to transmit the signal. (charite.de)

The cuff electrode fits around a branch of nerve under the tongue, like a tiny cuff. (hopkinsmedicine.org)
