Norepinephrine ( INN ) (abbreviated norepi or NE ), or noradrenaline ( BAN ) (abbreviated NA , NAd , or norad ), is a catecholamine with multiple roles including as a hormone and a neurotransmitter . [ 3 ] Areas of the body that produce or are affected by norepinephrine are described as noradrenergic . The terms noradrenaline (from the Latin) and norepinephrine (derived from Greek) are interchangeable, with noradrenaline being the common name in most parts of the world. However, to avoid confusion and achieve consistency, medical authorities [ 4 ] have promoted norepinephrine as the favoured nomenclature, and this is the term used throughout this article.

Epinephrine (also known as adrenaline or adrenalin ) is a hormone and a neurotransmitter . [ 1 ] Epinephrine has many functions in the body, regulating heart rate , blood vessel and air passage diameters, and metabolic shifts; epinephrine release is a crucial component of the fight-or-flight response of the sympathetic nervous system . [ 2 ] In chemical terms, epinephrine is one of a group of monoamines called the catecholamines . It is produced in some neurons of the central nervous system, and in the chromaffin cells of the adrenal medulla from the amino acids phenylalanine and tyrosine . [ 3 ] [ edit ] Medical uses Epinephrine
Serotonin ( pron.: / ˌ s ɛr ə ˈ t oʊ n ɨ n / ) or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter . Biochemically derived from tryptophan , serotonin is primarily found in the gastrointestinal (GI) tract, platelets , and in the central nervous system (CNS) of animals including humans. It is popularly thought to be a contributor to feelings of well-being and happiness . [ 5 ] Approximately 90% of the human body's total serotonin is located in the enterochromaffin cells in the alimentary canal ( gut ), where it is used to regulate intestinal movements. [ 6 ] [ 7 ] The remainder is synthesized in serotonergic neurons of the CNS, where it has various functions. These include the regulation of mood , appetite, and sleep. Serotonin also has some cognitive functions, including memory and learning.
Dopamine Functions By Dr Ananya Mandal, MD Dopamine is a neurotransmitter released by the brain that plays a number of roles in humans and other animals. Some of its notable functions are in: movement memory pleasurable reward behavior and cognition attention inhibition of prolactin production sleep mood learning

What's Your Type? We're each a mix of all four of Helen Fisher's relationship categories, but we express some traits more regularly than others. For example, you might primarily be an Explorer and secondarily a Negotiator, but then not have much Builder in you. As you read on, you'll probably guess both your primary and secondary types, as well as those of your mate.
The cost of growing up on porn Guess what, guys? Turns out pornography -- the much-maligned bugaboo of feminists, prigs and holy rollers -- is nothing more than good, not-so-dirty fun. The proof comes from the University of Montreal, where recent research showed that connoisseurs easily parse fantasy from reality, shudder at the idea of dating a porn star (what would Maman think?) and wholeheartedly support gender equality. "Research contradicts anti-pornography zealots," gloated a column's headline in the Calgary Sun. So, I've been contradicted.
Helen Fisher's Types: Explorer, Builder, Director, Negotiator In a previous post I wrote of a personality and matching test at Chemistry.com that was developed by researcher Helen Fisher. We are already seeing some possible patterns in how her types correspond to socionic types, and I encourage readers to take the test if they haven't already and share their results in that post. The best introduction to Fisher's research is this half-hour interview with her by Nicole Simon. Here Fisher talks about the history of her research, her main findings, and the types themselves. Each type is supposedly related to one of four chemicals that broadly influences personality: dopamine (a neurotransmitter), serotonin (neurotransmitter), testosterone (hormone), and estrogen (hormone). Explorer : (more dopamine expression) -- risk-taking, curious, creative, impulsive, optimistic and energetic

You complain that your boyfriend lies to you. "Is this your 'victim story'?" Dr. Phil asks you warily. Your boyfriend admits to lying . "Is this something you do because you're gutless?" Dear Reader, Get A Life
There's always an explanation: A 22-year-old college grad wants to hold out for the right job rather than jump into an underpaid makeshift position. Rents are so inflated, a 25-year-old moving out of her boyfriend's apartment couldn't possibly afford a place of her own. With two bedrooms to spare, parents can rehouse the kids and everyone will benefit. Whatever the reason, young adults are returning home in increasing numbers—following graduation, the dissolution of a relationship or the loss of a job. They often live rent-free and subsidized, with no scheduled date for departure. But while much attention has been paid to live-at-home "adultescents," little has been said about their parents, many of whom are Baby Boomers who greet their boomerang kids with open arms.

Every journey begins with a single step. The journey of the soul can sometimes be a difficult one, and sometimes be an easy one. Of the different ways our souls may choose to make those journeys, taking the road that leads through our sexuality can be one of the most troublesome, as well as one of the most rewarding.
