How to increase serotonin in the human brain without drugs

How to increase serotonin in the human brain without drugs
For the last 4 decades, the question of how to manipulate the serotonergic system with drugs has been an important area of research in biological psychiatry, and this research has led to advances in the treatment of depression. Research on the association between various polymorphisms and depression supports the idea that serotonin plays a role, not only in the treatment of depression but also in susceptibility to depression and suicide. The research focus here has been on polymorphisms of the serotonin transporter, but other serotonin-related genes may also be involved.1–5 In the future, genetic research will make it possible to predict with increasing accuracy who is susceptible to depression. Much less attention has been given to how this information will be used for the benefit of individuals with a serotonin-related susceptibility to depression, and little evidence exists concerning strategies to prevent depression in those with such a susceptibility.

Facial Action Coding System Muscles of head and neck. Facial Action Coding System (FACS) is a system to taxonomize human facial movements by their appearance on the face, based on a system originally developed by a Swedish anatomist named Carl-Herman Hjortsjö.[1] It was later adopted by Paul Ekman and Wallace V. Friesen, and published in 1978.[2] Ekman, Friesen, and Joseph C. Zinc Oxide Benefits: A Safer Sunscreen + So Much More For more than 2,000 years, we’ve turned to zinc to help deal with burns and wounds. Today, zinc oxide benefits are even more broad, but looking back (way back), records show that zinc itself was first used in natural healing skin salve called Pushpanjan. This was first described in ancient Indian medicinal scripts around the year 500 B.C. (1) According to the Official Publication of The International Association of Asethetics, today zinc oxide is a key active ingredient in many diaper rash creams, calamine lotions, mineral sunscreens (including some of the best sunscreens), vitamin supplements and acne treatments sold in drug stores or prescribed by doctors.

This Image Can Trick Your Brain And Make You See It In Color Perception is a fickle thing. As good as our senses are at keeping us alive, they can often mislead and deceive us. Here’s a great example of that which you can try at home, featured in the new BBC Four series, Colour: The Spectrum of Science. Check out the video below, follow the instructions and see a black and white image turn into a full-color image of a landscape. It’s all to do with our cone cells, one of the two types of photoreceptors within our eye’s retina, which are responsible for color vision. Clear Advice on Eye Diseases The only way to cure cataracts­—a clouding of the lens of the eye that impairs vision­—is with surgery to replace the bad lens with an artificial one. Though the procedure is very safe and effective, some doctors recommend needless tests or push newer types of lenses that pose risks. Skip unneeded presurgery tests Cataract surgery, usually performed as an outpatient procedure, requires only a local anesthetic to numb your eye. Research shows that for most people the only pre-op requirements are that you be free of infection and have normal blood pressure and heart rate. Yet many doctors routinely order other tests, including blood counts and electrocardiograms, as would be necessary before a major procedure.

Types of Sound Healing Techniques and the Benefits of Sound Therapy The concept of sound healing as an alternative medicine might raise some eyebrows. After all, it is a little hard to understand how sound waves and vibration can help your body heal. But this alternative method of healing indeed works. Let’s take musical sound, for example. Music has long been known to be therapeutic and has been used as a sound healing technique since ancient times. Greek philosophers have attested to its healing powers.

Richard A. Muller: The Case Against Global-Warming Skepticism Are you a global warming skeptic? There are plenty of good reasons why you might be. As many as 757 stations in the United States recorded net surface-temperature cooling over the past century. Many are concentrated in the southeast, where some people attribute tornadoes and hurricanes to warming. The temperature-station quality is largely awful. The most important stations in the U.S. are included in the Department of Energy's Historical Climatology Network.
