Brain chemistry

In short, love makes us dumb. Dopamine, which runs the reward pathways in our brain, is great in moderate doses, helping us enjoy food, exciting events, and relationships. So are emotions, such as sadness, grief, and stress.

Recent studies on party drugs such as MDMA and GHB shows that oxytocin may be the hormone behind the feel-good, sociable effects these chemicals produce. They can also have a larger impact on the nervous system, which means that people can develop conditions such as tremors and neuralgia as a result of an alteration to Brain chemistry fundamental chemistry of the brain.

The evolutionary basis for this stems from our need to reproduce, a Brain chemistry shared among all living things. Modifying Neurotransmission with Drugs Many neurological nur-a-LA-je-kal conditions, ranging from emotional disorders, such as depression, to movement disorders, such as Parkinson disease, are associated with imbalances Brain chemistry certain neurotransmitters in the brain.

One of the hottest debates surrounds a condition known as attention deficit hyperactivity disorder ADHDwhich usually is diagnosed in childhood. When the brain tells the body to do something, such as to sit down or run, this also sets a chemical process in motion.

Brain chemistry reproduction, organisms pass on their genes, and thus contribute to the perpetuation of their species. In most cases, while medications can help to decrease symptoms, more complete and long-lasting relief is achieved through therapy that helps with behavior change.

Katherine Wu is a third-year graduate student at Harvard University. They now know that all the feelings and emotions that people experience are produced through chemical changes in the brain.

Nicotinefor example, is heavily involved with the neurotransmitter dopamine. What happens when brain chemicals are modified is described in the three examples of neurotransmitters serotonin, dopamine, and gamma-aminobutyric acid below.

A medication called L-DOPA, which the brain can convert into dopamine, often helps control these symptoms. It seems that our friendly cohort of hormones is also responsible for the downsides of love. A Cascade of Chemicals Every day, researchers are learning more about the chemicals that the neurons NUR-ons in the human brain use to communicate with each other.

In the end, everyone is capable of defining love for themselves. Repeated use of Ecstasy may lead to depression or other problems over time, since the neurons can "bounce back" only so often. And addicts going into withdrawal are not unlike love-struck people craving the company of someone they cannot see.

Brain Chemistry Neurochemistry Photo by: As a result, there is more serotonin available, and this sometimes helps alleviate the symptoms of depression. Based on her meetings with Hector, she decided to prescribe a type of medication known as an antidepressant. And finally, what would love be without embarrassment?

Sure enough, it did. He had a hard time making friends, he was not interested in his schoolwork, and he spent most of his time hanging out in his room alone.

These "chemical communicators," or neurotransmitters, are the "words" that make up the language of the brain and the entire nervous system.

Risk takers, for example, often have fewer dopamine receptors in their brains, which can mean that they have to work harder for a sense of satisfaction and reward. Norepinephrine, epinephrine, and other hormones produced by the adrenal gland are involved in the "fight or flight" response of the body to stress.

Testosterone and estrogen drive lust; dopamine, norepinephrine, and serotonin create attraction; and oxytocin and vasopressin mediate attachment.

These positive feelings are taken to an extreme in this case, causing the user to dissociate from his or her environment and act wildly and recklessly.

An illegal drug known as "Ecstasy," or MDMA, also changes the level of serotonin in the brain, but much more radically. Some chemical compounds appear to have long term effects.

It causes the serotonin-releasing neurons to dump their contents all at once, which floods the brain with the chemical and produces feelings of extreme happiness and hyperactivity excessive activity.

What Is Brain Chemistry?

The Friend Zone Last but not least, attachment is the predominant factor in long-term relationships. Serotonin Many studies have linked low levels of the neurotransmitter serotonin to depression, impulsive and aggressive forms of behavior, violence, and even suicide.

Sexual arousal but not necessarily attachment appears to turn off regions in our brain that regulate critical thinking, self-awareness, and rational behavior, including parts of the prefrontal cortex Figure 2. At the same time, many legal and illegal drugs, such as the nicotine in cigarettes and the street drugs heroin and cocaine, work by changing neurotransmitter levels.

It is believed that variations in brain chemistry may explain a variety of behavioral disorders and phenomena. This may push them to engage in risky behaviors.

Others feel that children with ADHD have been under-diagnosed for many years and only more recently are being appropriately diagnosed and treated.Science in the News Opening the lines of communication between research scientists and the wider community What we do know, however, is that much of love can be explained by chemistry.

So, if there’s really a “formula” for love, what is it, and what does it mean? Brain scans of people in love have actually shown that the primary.

Love, Actually: The science behind lust, attraction, and companionship

Brain Chemistry Labs' Movie Selected for Newport Beach Film Festival It was a successful world premiere of the documentary Toxic Puzzle, featuring Brain Chemisty Labs’ Paul Alan Cox, his team in Jackson Hole and collaborators from around the world.

Aug 30,  · Brain chemistry is the Brain chemistry and processes that allow the brain to work. Everyone's brain chemistry is a little different, and. Brain chemistry is the sum of all the chemical messaging that takes place in the brain, which allows it to carry out its daily functions, such as generating movement, speaking, thinking, listening, regulating the systems of the body, and countless others.

Jun 14,  · Serotonin is one of the chemical messengers that nerve cells in the brain use to communicate. Modifying serotonin levels is one way that antidepressant and anti-anxiety medications are thought to work and help people feel better.

But the precise nature of serotonin’s role in the brain is largely. Neurochemistry is the study of neurochemicals, including neurotransmitters and other molecules such as psychopharmaceuticals and neuropeptides, that influence the function of neurons.

This field within neuroscience examines how neurochemicals influence the operation of neurons, synapses, and neural networks.
