synapses use neurotransmitter to carry information from cell to cell. (flashcardmachine.com)

Now they are more concerned with other neurotransmitters and hormones such as serotonin, dopamine, cortisol, noradrenalin, and how they regulate and are regulated by proteins. (lu.se)

There are strong links between the serotonin and dopamine systems, both structurally and in function. (medicalnewstoday.com)
Methamphetamine is structurally similar to the neurotransmitter dopamine . (psychologytoday.com)

Drugs that are known to reduce dopamine activity (e.g. antipsychotics) have been shown to reduce people's desire for pleasurable stimuli, despite the fact that they will rate them as just as pleasurable when they actually encounter or consume them. (psychologistworld.com)
Other theories suggest that the crucial role of dopamine may be in predicting pleasurable activity. (psychologistworld.com)
Nearly all pleasurable experiences - from eating a good meal to having sex - involve the release of dopamine. (healthline.com)

the catecholamine family includes dopamine, norepinephrine, and epinephrine. (medscape.com)
rather, plasma fractionated catecholamines and 24-hour urine fractionated catecholamine should be ordered since rarely will pheochromocytomas and paragangliomas only secrete dopamine. (medscape.com)

It is thought that this overload of dopamine gives the user the cocaine "high. (sciencedaily.com)

Like dopamine, serotonin can influence people's moods and emotions, but it also helps regulate digestive functions, such as appetite, metabolism, and gut motility. (medicalnewstoday.com)

What are the five steps for the release of neurotransmitters? (flashcardmachine.com)
Effects of polychlorinated biphenyls on dopamine release from PC12 cells. (cdc.gov)

Thus a signal is sent coursing through the body, and that causes the importance of the movement to be understood, and replicating said action takes precedence - that is how dopamine works in a nutshell. (elevate88.com)

When a nerve wants to talk to another nerve, it releases a neurotransmitter," explains Todd Levine, MD, chief medical officer for CND. (medscape.com)
It is a neurotoxin that prevents the nerve from releasing acetylcholine, which is a neurotransmitter that tells the muscle to contract. (oncolink.org)

Dopamine is the body's habit development tool, and it rarely ever leads to the development of a compulsive and uncontrollable addiction. (elevate88.com)

The neurotransmitter has also been associated with mental illness and imbalances because of how much control it has over the mind and body. (elevate88.com)

We distinguished 62 neuronal subtypes producing glutamatergic, dopaminergic or GABAergic markers for synaptic neurotransmission and harboring the ability to engage in task-dependent neurotransmitter switching. (nature.com)
