In addition to the many ways music activates the brain, neurological studies show that happy tunes, with a fast tempo and often written in a major key, make us breathe faster. Sad songs, with a slow tempo and written in a minor key, slow the pulse.

What might cause a pins-and-needles sensation in my fingers?
Anthony Komaroff, MD, Internal Medicine, answeredThe sensation of "pins and needles" is usually due to a nerve problem.
The medical term is parathesias. It may also include shooting pains, numbness or a heavy feeling in an arm or leg. Common causes include:
- Nerve compression
- Vitamin B12 deficiency (which impairs nerve function)
Carpal tunnel syndrome is due to the compression of a major nerve (called the median nerve) that travels through a narrow area (the carpal tunnel) in the wrist. Besides pins and needles, some people experience weakness, particularly in the thumb.
Repetitive motion may be a risk factor for carpal tunnel syndrome. But studies that looked at people who use repetitive hand or wrist motions have been mixed on whether their risk of carpal tunnel syndrome is truly increased.
Treatment options for carpal tunnel syndrome include:
- Treating or removing any underlying trigger
- Wearing a splint that keeps the wrist relatively straight
- Cortisone injections
- Surgery (as a last resort)

What are the effects of different levels of serotonin?
Sharine Forbes, Gerontology, answered
Serotonin, which has been shown to influence many of the brains cells, is made through a biochemical process in the brain but for the most part is found in the digestive tract and in the blood platelets. As a neurotransmitter, Serotonin is responsible for feelings of happiness, contentment and overall mood. When concentration levels of serotonin are high then feelings of happiness ensue. When levels of Serotonin are low an individuals overall mood decreases as they become irritable and sad. Additionally 5-HTP, which can act as a serotonin precursor to stimulate the secretion of serotonin production in the brain. If the levels of serotonin absorbed during reuptake are extreme then this also can lead to feelings of sadness. As a result, serotonin can be linked to have influences on different behaviors such as, but not limited to, overall mood. The overall composition of serotonin is essentially a combination of tryptophan hydroxylase and tryptophan, which makes 5-hydoxytryptamine, also known as serotonin.
