Being active raises the levels of serotonin and dopamine in the brain.
Bromocriptine-Also known as Parlodel, it is a dopamine receptor agonist used to treat galactorrhea by reducing levels of the hormone prolactin and is also used to treat Parkinson's disease.
Carbidopa enables L-dopa to be converted to dopamine after the L-dopa enters the brain, thereby lowering the oral dose and decreasing side effects.
Cocaine increases the amount of dopamine available to receptors in the brain.
Domperidone increases prolactin secretion indirectly, by interfering with the action of dopamine.
Dopamine and other neurochemical transmitters appear to be implicated in bipolar disorder, and these are under investigation as well.
Dopamine blocking drugs are frequently the first choice of treatment, Eg haloperidol chlorpromazine, trifluoperazine, sulphiride and pimozide.
Dopamine is a chemical that aids in the transmission of nerve signals.
Dopamine is associated with feelings of pleasure.
Dopamine Systems in the Brain There are a number of collections of nerves in the brain that release dopamine Systems in the Brain There are a number of collections of nerves in the brain that release dopamine.
For a number of smokers, the first cigarette of the day is especially pleasurable and one that they look forward to having, since it gives their brain its first "hit" of dopamine.
In turn, nigrostriatal dopamine has been suggested to be critical for the execution of sequential movements.
Increased dopamine levels were detected, confirming some experts' opinion that gaming is chemically addictive.
It also regulates neurotransmitters, helping your body maintain an appropriate balance of serotonin, melatonin, and dopamine.
It decreases the amount of dopamine in the brain and increases the amount of serotonin.
It increases your body's dopamine levels in the same way that heroine, cocaine, and amphetamines do.
It interferes with the normal path of a brain chemical called dopamine.
It is now known that in some other parts of the brain in those labeled schizophrenic there is in fact rather little dopamine activity.
It works by blocking the receptors for opiates and preventing the release of dopamine so an addict no longer gets pleasure from the drugs.
Levodopa (L-dopa) is a medication that is converted to dopamine in the brain.
Levodopa, the metabolic precursor of dopamine, relieves the symptoms of Parkinson's disease presumably by being converted to dopamine in the brain.
Neuroimaging studies have shown that tic disorders are related to abnormal levels of neurotransmitters known as dopamine, serotonin, and cyclic AMP in certain parts of the brain.
Nicotine addicts a person because it increases the dopamine levels in the brain.
Nicotine is a physiologically addictive; research has shown that it increases the levels of dopamine, a neurological transmitter, in the smoker's brain.
Once in the brain, it is converted to dopamine and thus can replace the dopamine lost in Parkinson's disease.
Once you get away with it - with financial infidelity - then you move to infidelity for the "thrill seeking" and endorphin and "dopamine high."
One such chemical, dopamine, has been found to play an especially important role in the disease.
Over time, dopamine and oxytocin stabilize and we don't feel the same high that we once did at the start of the new relationship.
Parkinson's disease-A slowly progressive disease that destroys nerve cells in the basal ganglia and thus causes loss of dopamine, a chemical that aids in transmission of nerve signals (neurotransmitter).
Parkinson's patients do not produce enough dopamine, which affects co-ordination.
Phenylalanine and tyrosine are needed to produce catecholamines such as adrenaline, noradrenaline and dopamine.
Research into dopamine agonist skin patches is in progress.
Researchers have found that Ecstasy causes extensive damage to key brain cells, called dopamine neurons.
Risperdone and clonazepam, which address a dopamine imbalance, can be added to SSRIs if an SSRI drug does not satisfactorily control symptoms.
So our idea is to try and change these cells specifically into ones that make dopamine or insulin.
Some studies suggest that the tics in Tourette syndrome are caused by an increased amount of a neurotransmitter called dopamine.
Subsequent cigarettes aren't as pleasurable, since the nicotine doesn't fire the dopamine in the brain to the same extent.
Taking certain drugs such as amphetamines, dopamine, corticosteroids, and phenothiazines may increase or decrease growth hormone secretion.
Test-tube experiments on brain tissue from autopsy confirmed this dopamine deficiency.
That's because when we fall in love our brain releases dopamine and oxytocin, two "feel good" chemicals.
The baseline mean plasma prolactin level was nearly doubled in the drug responders, suggesting reduced brain dopamine activity.
The body converts phenylalanine into l-tyrosine, another amino acid, which is the precursor to brain chemicals include dopamine, norepinephrine and epinephrine.
The brain makes dopamine from the amino acid tyrosine.
The chemical dopamine is then released in the brain, which leads to feelings of contentment.
The disease is associated with a lack of dopamine, a brain communication chemical.
The dopamine allegations are debatable as well.
The l-theanine is believed to stimulate alpha brain waves, which contribute to states of relaxation and assist in the formation of GABA, which then influences the brain's "feel good" transmitters, serotonin and dopamine.
The mainstay of treating Parkinson's disease is to replace dopamine in the brain.
The nicotine triggers the brain to produce higher levels of dopamine, and this creates a feeling of well-being.
These are neurons that produce the chemical messenger dopamine.
These cells produce dopamine - a chemical which plays a key role in movement.
These chemicals include serotonin, norepinephrine, and dopamine.
These hormones are often referred to as feel good hormones and include serotonin and dopamine.
They studied damage to part of the rat brain called the substantia nigra, where the cells normally release a substance called dopamine.
They work by reducing the action of a particular chemical messenger in the brain called dopamine.
Turning to the right or left is strongly correlated with turning toward the side of the brain that has less dopamine, an important brain hormone.
Uprima is absorbed under the tongue, stimulating the brain chemical dopamine, which starts the signal for an erection.
When you are attracted to someone your brain releases the drug dopamine giving the same reaction that taking cocaine or speed would create.
